These days, if you're not at least on two or three major social networks, some people say you don't exist. I have to agree with that, especially since I got a Hi5 account some time ago and didn't spend any time on that site for a very long time. Fortunately, I had contact data entered right, and some of my high school classmates were able to track me down and get in touch with me, since we're having a reunion this May. On the other hand, I still can't digg Twitter, although a lot of people around me say this is the new Internet God. Well, for those of you who love Twitter, there's this iPhone Lounge software...

...a piece of code that claims to be Goose Apps' first product for the iPhone, and "taking the social networking environment of Twitter and extending it into a versatile, flexible, yet easily navigated user experience." Sounds like big words to me, but let's see more of the official description now, shall we?

"Lounge allows you to not only write and read your public and private tweets as well as direct messages, it enables you to compose and view tweets by category as well. You can quickly create your own "smart categories" using Twitter's own search syntax, much like "Smart Playlists" in iTunes or "Smart Mailboxes" in Mail on OS X. Staying current with tweets between a specific set of users, or posts using any combination of words, or even a combination of both, is just a tap away. If you can search for it using Twitter, you can save those searches in Lounge.

Lounge lets you easily browse tweet details, such as linked web sites, referenced users, hashtags, and provides access to the author's profile date, such as web sites, friends, tweets, all on the fly within the application. Thanks to Lounge's thoroughly consistent sliding lists design, recursion is virtually unlimited - just dive into a chain of tweets and users and zoom back out."

Additional features include landscape orientation, and multiple accounts support, as well as the ability to choose the interface style and size you want.

The price? For now, the Mac desktop client comes for free(still a Beta version), and the iPhone Lounge software is available for $1.99 via the App Store.

Too many years ago, a great company called 3dfx came up with the idea of having more than one GPU work on rendering images to your screen. Unfortunately, they were ahead of those days, and despite the fact they had the world at their feet, ended up by being engulfed by NVIDIA. Now, we may see multi-GPU technology on Apple's iPhone, and I think if this happens, those who will enjoy probably the most powerful handheld gaming console of the year will have to thank the "Voodoo spirit" for it...

The press release that made everyone go "WOW" is entitled "Imagination Technologies launches advanced, highly-efficient POWERVRâ„¢ SGX543MP multi-processor graphics IP family" and describes "the first POWERVR SGX graphics IP core with multi-processor (MP) core support" that comes in 2-core and 16-core variants.

According to Tony King-Smith, VP marketing Imagination Technologies, "The performance delivered by our latest POWERVR SGX543MP family is the ultimate statement of the highly linear scalability of our unique Series5XT architecture. With the ability to combine up to 16 SGX543 GP-GPU cores on a single SoC, we are now able to deliver capabilities to our licensing partners previously only thought the domain of the discrete GPU chipset vendors, while maintaining our unrivalled power, area and bandwidth efficiency." He may not say "we're going to send this to Apple for the iPhone 3.0 hardware revision," but that's what a lot of people expect to happen, anyway.

While it's obvious we won't have 16-core graphics on the iPhone 3.0, the capabilities of this solution are pretty impressive: "At 200MHz core frequency an SGX543MP4 (four cores) will deliver 133 million polygons per second and fill rates in excess of 4Gpixels/sec. Higher frequencies or a larger number of cores each deliver more performance. At 400MHz core frequency an SGX543MP8 (eight cores) will deliver 532 million polygons per second and fill rates in excess of 16Gpixels/sec."

While some expect the dual-chip solution to power the new iPhone, others claim this to be destined for the Apple Tablet PC we keep hearing about. To be honest, I'd go with the computer, and leave the phone as it is. Just think about the battery life - are we going to have a dual-GPU iPhone with 20 minutes 3D games autonomy? Thanks, but no, really.

A few days ago, the Internet was boiling. Rumors, of course, that was the reason. Nothing special, so far. What kind of rumors? Well, iPhone 3.0 rumors! Now, it's all official, since the March, 17 event is behind us, and there's a page with details right on Apple.com.

To spare you the effort of going through all the mumbo-jumbo on that page, here's the essential part:

"With the new SDK, members of the iPhone Developer Program can build applications that do even more. Developers will have the tools to enable in-app purchases — like subscriptions, additional game levels, and new content. They can also create apps that connect peer to peer via Bluetooth, communicate with hardware accessories, and use the Apple Push Notification service to provide alerts."

Finally, we'll get copy-paste! It was about time, Apple, it was about time...so here's the brief list of hot features to arrive this summer(apple claims over 100 new features will be introduced):

- Search your iPhone
- Cut, copy, and paste
- Send photos, contacts, audio files, and location via MMS
- Read and compose email and text messages in landscape

Unfortunately, MMS messaging will only be available to iPhone 3G users, and additional fees may apply. The new iPhone SDK and iPhone 3.0 Beta software can be downloaded already by iPhone Developer Program members from the iPhone Dev Center now, while the rest of us will have to wait until June, I guess.

Having Internet access on your mobile without being able to make any online purchases isn't exactly what I would consider "great," and today the time has come for some iPhone mobile transactions. No, I won't buy anything using my iPhone, especially because I don't have an iPhone at this time, but talking about Skorpiostech's and Dragon Foged Software's Transactions app is something without any special hardware requirements...

This application enables its users to make credit card payments through their iPhone and iPod Touch, and there are two payment gateways currently supported - Authorize.net and the notorious PayPal. Obviously, you'll need to have an account setup with the one you want to use before making any payments, but I am sure that can't be a problem.

The features of this iPhone mobile transactions software allow you to charge your credit card wherever you are, as long as some kind of Internet connection is available for your gadget, while transaction logs can be exported to a computer. Even more, your confidential data can be easily secured by Apple's Keychain app, and Transaction also offers various password protection settings.

At last, you should also know that Transaction can be used over any Wi-Fi, 3G, or EDGE connection, being able to import data right from your iPhone address book, and a free to use Lite edition is also available, next to the $30 Pro one. More information about the program can be found here.

Why would you use your iPhone to take some serious pictures, that's beyond my understanding capabilities, but if you're into doing it, at least do it right! Obviously, taking some photography classes would be a total waste of time and money, so why not have a quick iPhone photography guide available right on your smartphone?

Here's the official description of this interesting product for your iPhone/iPod Touch: "Poses Volume 1 contains 368 individual color images of attractive, popular poses that any model can quickly and easily adopt. The application has a unique 'Fit Pose' feature that assists in getting the subject's pose to closely match any professionally-posed example from the application. The guide's eight models, wearing plain dance costumes, were photographed against a clean white backdrop, making it easy to see every aspect of every pose. Pose examples are organized by type (seated, standing, kneeling, etc.), simplifying the search for the "right" pose."

So far, so good - only that they forget one thing - to get professional pictures, you need a professional camera. Come on, people, why waste some hot chick's images at 2 MP? I see absolutely no reason, unless your iPhone is the only device capable of taking pictures in the city, and that chick is going to fly away in a few minutes!

Anyway, if you'll enjoy the first volume, now available via the App Store for $9.99, you may be interested in the other two ones. Why? Well - "Poses Volume 1: The First Female Collection" is a product of PhotographyTips, the Internet's #1 guide to better photography. It is the first in a series of three collections, which comprise in total 1,104 individual posed images. Volumes 2 and 3 are in the approval stages and will be released soon." - that's why!
