First of all, let me remind you that jailbreaking your iPhone 3G, just as it was the case with the old iPhone, will probably void your warranty, so be aware of this - if you think the benefits you will get are worth this price, go ahead! Here's what you should do...
Get the Pwnage Tool 2.0, and then be careful to follow the instructions there and ask around to know all there is to know before taking this step. While this tool only supports firmware 2.0, there's one drawback that may force a lot of people to wait - Pwnage Tool 2.0 is able to jailbreak and unlock older iPhones, but it only jailbreaks the iPhone 3G and iPod Touch, so if you got the iPhone 3G with a service plan (obviously you did), you won't be able to drop it just yet...
Well, I guess this is it, so if you're one of those enjoying to walk on the edge, go ahead and hack your iPhone 3G, but if you ask my opinion, I advise you to wait for at least a few days and see what happens with the brave ones going in first!
