The 3G model of iPhone was released first on June 19, 2009, before the releasing of the first Black Berry Bold and had almost 4 millions of units sold.

The iPhone OS 3.1.2 operating system  was released in October 8, 2009 and it is developed by Apple Inc. specially for this smart phone and iPod Touch. It uses the Darwin base and have four abstraction levels for particular sets of functionality: the Core OS level, the Core Services level, the Media level and the Cocoa Touch level. This operating system uses less than 240 MB of he phone memory storage. The name of this operating system became official in March, 2008, as a reference to the Mac OS X.

The 3G model have an internal rechargeable battery that can't be removed, with a power of 3.7 V 1150 mAh, also Li-On polymer.

Same as the original, the 3G iPhone uses a Samsung 32 bit RISC ARM processor of 620 MHz that can be under clocked down to 412 MHz. The graphics processing unit with a PowerVR MBX Lite 3D chipset.

This device can be found, as an option, with a flash memory of 8 GB or 16 GB capacity, with 128 MB of DRAM.

The display is the same at every model of iPhone Touch: 320 x 480 pixels, 89 millimeters, a 2:3 aspect ratio and a 18-bit LCD that can provide up to 262 144 colors. At 163 pixels per inch.

The 1^st generation of iPhones, also known as Original, had enhanced data rates for GSM evolution, a digital mobile phone technology that will allow the improved data transmission rates, as an annex to the top of classic GSM. This technology it is also named, in its short form, as EDGE. With the second generation of iPhones, Apple Inc. added to this smartphone an universal mobile telecommunications system, UMTS, as a part of the International Telecommunication Union, being a totally and complete network system. This technology will allow users to listen radio, authenticate via USIM cards ore use a web network on a 3,6 MB per second band width. Beside this feature, the 3G model of iPhone incorporates also a high speed downlink packet access which allows the network to have a high data transfer capacity and speed with 7,2 MB per second, but limited to 384 kb per second upload.

This smart phone was released after couple of months of rumors, in January 9,  2007 and first was introduced in U.S.A, and after its real success in 22 countries of Europe and Asia. On March 17, 2009, was announced a new version of the iPhone OS, the operating system used on this model, and released at the middle of 2009.

At the hardware part, iPhone 3G is almost perfect for anybody. Its case is made completely  from a hard plastic material, despite the Original which have some aluminum parts. The touchscreen has 9 cm dimensions and it is made from liquid crystals with 320 x 480 pixels and 160 ppi. The display contains also a scratch resistant glass and can render exactly 262 144 colors. For a multi touch sensing, the screen is projected for  a bare hand or a touch with multiple fingers. A fingerprint resistant coat it is also included in the features of this display. Three sensors are integrated so that the battery to be properly saved and the user more comfortable when he is watching videos or photos.

The 3G iPhone is available with a full plastic back, for an increased in strength of the 3G signal.  The 8 GB model is available in black color and the 16 GB  either in white or in black. The 3GS iPhone is available in both colors.

Even if the Original model had a headphone socket incorporated which had a sunken area into the case, which made it compatible only with the Apple headphones, at the 3G model this problem was solved by adding a flush mounted headphone socket.

The 3G model is capable to storage up to 32 GB, but can be found also in 8 GB and 16 GB capacity varieties. The processor it is made by Samsung and  have an ARM7 core for Jazzele acceleration. The flash memory it is 128 MB of DRAM. For connectivity it uses Bluetooth 2.1+ EDR , have a built in speaker and hardware volume controls. It also have the Nike+  Kit that measures the foot steps and record them.



For power it has a built in rechargeable Li-On polymer battery rated for 36 hours of continuous music or 6 hours of video replaying.

The dimensions are pretty small, the iPhone 3G measuring only 110 x 61.8 x 8.5 millimeters to a weight of 115 grams.

To prevent the hack or the third party applications, also called  jail breaking, the iPhone's operating system is designed to launch and run only software that have a cryptographic signature approved by Apple. Also the phone prevent access to media player and web since it is activated as an Apple device to an authorized carrier. Despise this facts, there are a lot of programs cracked for this phone and a lot of methods to unlock it, by replacing the   Firm Ware software with a modified version that don't need the signature check.

Even if it is one of the most popular smart phones from the market, iPhone have some user report problems at the active. The most troubles was found on the 3G, simple iPhone, and the 3GS models.

If your on your personal iPhone doesn't appear iTunes or you just aren't  able to sync it, you should do some certain steps before walk with it to an appropriate service.

First of all, you might need to check the battery status and if it isn't in need of a new recharge. If everything is ok at this chapter, you can check the second step from this guide and try a different USB port for your iPhone. Disconnect the device from the usual computer's slot and connect it to another, just to see if it is not from here the problem. Also try to be sure that it is an 2.0 USB type and not an elder version.

If your iPhone still not work, try to reset it by turning it off and on. Press and hold for three seconds the Wake/ Sleep button, which you will found in the top of your smart phone  until  a slider appears to your display. You will need now to slide this red slider. After you completed this task, press again the Wake/ Sleep button until you will be able to see on the screen the Apple logo. Be careful to enter your SIM card Pin correctly, because if you will wrong it three times you will need to contact a carrier to enable your card again.

If it still not working, you will need to restart the personal computer and try to reconnect again the iPhone to it. Also you can try to download and reinstall the latest version of iTunes software from the Apple's Inc. official site.

Another unusual but pretty often met is when the user can't make or receive calls, send and receive SMSs, or access e-mail and browse the web. To solve this problem you will need, first of all to check your signal indicator from the status bar which can be found at the top of the screen. If there isn't any bars or you can see a message that it is telling you that there is no service available, try to move from that spot to a different location or near an open window or outdoors.

Try to be sure that you are in a covered area asking some appropriate person if his signal is ok. If you are near a computer, you might check your career's official website to see if you are in a network coverage area.

If everything it is ok until now but you still can't receive any phone call or text message , make sure that the air plane mode is on. Go in the Home Screen Menu and choose Settings and switch the Air Plane mode off or on. Wait 15 seconds and if you still didn't received any sign of functionality from your iPhone, turn this option to its initial statement. Make sure that you dial the right number, with the included area code when you try to attempt a phone call.

Try to reset your iPhone if you still encoring  troubles  by pressing the Wake/Sleep button and shutting it down. Make sure also if the position of the SIM card it is correct and it stays straight into its slot.  After you open again your iPhone, check the service again and see if you still have problems. You might need to call to your carrier assistant service and see if there aren't issues with the wireless service.

You need to know that original model of iPhone does not support MMs, this service being available only for 3G and 3GS models, and only if the carrier provides this kind of service. You can check your iPhone's system features on official Apple's site.

As the supreme troubleshoot you will need to restore and update your iPhone software if  all this guide steps made before didn't helped. The restore model it is just like on the iPods from second to third generation. Make sure that first of all you are backing up your iPhone files because yow will lost everything if you don't do that. For a better image think that you will reinstall an Windows or Mac OS X operating system to a mini personal computer. After you updated your iPhone, restore it and for sure it will be able to work.

Mac Mini is a desktop computer released by Apple Inc its basically characteristic being that it is a little too small for a desktop computer, measuring only 16,5 centimeters square and 5,1 centimeters tall. It have only 1,31 kilograms and it have an external power supply, that measure a 3^rd of the size of the whole device.
<-300x250 Medium Rectangle - center->
This Mac Mini is the 1^st MacIntosh product which don't include a mouse or a keyboard. It is designed for those who already have a monitor and other customers.

Upgraded in October, 2005, the Mac Mini have a 1, 33 GHz  or a 1,5 GHz processor PowerPC G4, an ATI Radeon 9200 graphic processor with 32 megabytes or 64 megabytes DDR SDRAM memory. The hard -drive, same as the elder models is an Ultra ATA of 40 or 80 GB that runs to 4200 rotations per minute. The memory is expandable to 1GB, but it is available in a one RAM slot with 256 MB SDRAM. The Air Port can be optional or integrated as a an IEEE 802.11.

The optical drive available for the current model of Mac Mini can read DVDs at 8x speed, CD-R at 16x and have the combo drive function. The minimum operating system required it is Mac OS X v 10.4.2, named also the Mac OS X Tiger, which is the 5^th major release of Apple's operating system for Macintosh.

Dimensions are the same at the both models, the elder one and the previous, and are 50.8 x 165.1 x 165.1 millimeters.

The last Mac Mini model can function with several operating systems designed for the architecture of Power PC. Any user can easy install the Debian Linux, but without the benefit of Adobe Flash because Adobe systems didn't developed a version for this environment.

Even if it has been entirely removed from the design of Mac Mini, modem  designed by  Apple is also available only that now it is external and USB based and costs almost 35 liras.

Although the design of  a Mac Mini is entirely handled by Apple, some of the components are planed and directed by Sparkfactor Design. First generation of this product included a built-in  iPod dock slot connector in its top but this feature was excluded at the initial release.

The iMac it is an Apple line released as a variety of MacIntosh desktop computers, which have the quality of being the principal part of Apple's consumer desktop contribution since they resigned this product into the profile market. It suffered, among the time, 4 big upgrades and evolved not only at the quality and the used technology but also at the exterior design. The actual model it is now thinner, even if it have the same shapes and forms a the elder iMac models. It also have an aluminum case and a black bordered glass for its display, and you can see a single screw on the entire body, which represents the slot access to the internal memory. The back is made from a solid material ant it is no longer removable.

The Aluminum iMac comes with an LCD as display, available in 4 dimensions: 20", 21.5, 24"or 27". It have an included hard disk with 2 optional capacities of 259 gigabytes  or 2 terra bytes and a Super Drive with a 8x capacity of re- writing.

The elder model had an 1,83 GHz Core Duo processor with 2 MB on-chip L2 cache, unlike the more youthful model  that is an 1,83 GHz T5600 Core 2 Duo available for the low- end 17" only, or a 2.0 GHz T7200 available for the high- end 17". Optional, you can also choose a 2,16 GHz processor or a 2,33 GHz for the 20 inch and the 24 inch models.



Since the release date, August 7, 2007, it used the Mac OS x v 10.4, now being available also with the immediately following version, the v10.6.

The initial model of iMac was the first released Macintosh that included an USB port, but being the only interface for peripheral built in it.  The unexpected success and popularity of this product helped the introduction of this interface among all the computer's industry.

Using this port, producers of peripherals could make products able to exist and perform in harmonious or agreeable combination with both Macs and PCs.

The iMac is  a line of Macintosh desktop personal computers, released by Apple Inc. The features that can be currently found in the Apple's iMac configuration are  Intel Core processors, GeForce nVidia graphic or ATI Radeon High definition  integrated cards. Also, the displays can be either 21,5 inch or 27 LCDs.

Although the elder models of iMac had a polycarbonate white case, the older generation have a shaped and styling enclosure. When you see them you can easily think to Apple's Cinema Displays, a product line of flat widescreen monitors, or to an iPhone. Following the success of the MacBook Pro, the designers used this model of assembly, incorporating in iMac an unibody case. Yet, the elder model of this product, the aluminum one, had a black back, made of plastic.

In a Steve note at the MacWorld conference from January 10, 2006, it was announced that the iMac will be the 1^st MacIntosh that will use and Intel Processor, in a Core Duo system. That was the moment when started a 6 month period of transition between PowerPc and Intel. Since the iMac G5, the only thing that changed was the processor's  speed , the price, the design or the features remaining the same.

The 1^st computers from this line, along with the MacBook Pro, represent the first Apple's computers with an Intel CPU. Since they introduced the iMac Core Duo, and had a real success, the other product lines have adopted this configuration, including the Mini Mac at the start of 2006, the MacBooks at the middle of the same year, followed immediately by Mac Pro, on August, and the Xserve in November.



In February 2006, users reported that the products have some video display problems, like random lines on screen or video bucking.  These major problems have been solved with an immediate software upgrade.

At the end of 2006, Apple Inc. introduced a version of  iMac that had a Core Duo chip inside and a much lower price. Also, they added a 24 inch model that can support a resolution of 1920 x 1200 pixels that stands for widescreen ultra extended graphics array and have a 16:10 screen aspect ratio. That represented the first iMac that could display HDTV video mode, a system that uses full frames just like a jpg picture, in 1080 TV lines of progressive scan. Also, they released  on this product and a VESA mount, a flat display mounting interface. With the exception of the 17 inch model, all the versions included also and a IEEE 802.11n-2009 draft card.

Making a comparison between the early 2006 models, the Intel Core Duo and the Intel Core 2 Duo models, released in the late 2006, we will review the technical configurations and we will figure that there aren't too many differences. They have both an white polycarbonate enclosure and can be found in a 17" 1440 x 900 and 20" 1680 x 1050 matte display form, all wide screen. Yet, the second model can be found also in a 24" 1920 x 1200 variant, also matte.

On the graphic card side we can see a major difference. The first model had an ATI Radeon X1600 graphic, with 128 MB SDRAM, or, as an option, with 256 MB available for the 20" model. The late model have either an Intel GMA 950 with 64 MB memory shared with the main one, either an ATI Radeon X1600, either a nVidia GeForce 7300 GT with 128 MB of GDDR3. The last model it is available and with 256 MB of GDDR3 SDRAM, only for the 24 inch models.

Both use a serial ATA hard drive with 160 GB or 250 GB capacity and 7200 rotations per minute. Optional, the user can acquire a  500 gigabytes one.



The earlier model had an 1,83 GHz Intel Core Duo processor with 2 MB on-chip L2 cache, unlike the younger model  that is an 1,83 GHz T5600 Core 2 Duo for the low-end 17" only, or a 2.0 GHz T7200 for the high- end 17". Optional, you can choose a 2,16 GHz processor or a 2,33 GHz for the 20 inch and 24 inch models.

The Air Port it is integrated in the both models and they are disabled by default. The later model have and a 24x combo drive, available as an optional for the low- end 17" only. Both, the first and the second model have as internal slot- loading an 8x Super Drive with 2.4x double layer recording for DVDs, rewritable DVDs and rewritable CDs.

Steve Jobs introduced in July, 2009, a fully restyle of iMac, providing an aluminum and matte glass design. The only screw that it is visible on this models it is right in front of memory slots and it is made to assure an easy access to them. The back it is now solid and black and it is not anymore removable. They totally removed the 17 inch model and introduced a 24 inch one.

In March, 2009, Apple Inc introduced a brush up to iMac product line with a USB port, a double RAM capacity, a slimmer restyled base and leaving only one FireWire Port.
