George Hotz has done it and released what we think is the first software based method for unlocking / jailbreaking iPhones running the latest firmware 1.1.3 for use on unauthorized wireless carriers. Though this sounds like something very clever and convenient as it unlocks iPhones directly from firmware 1.1.3 instead of having the need to downgrade like previous iPhone / iPod Touch jailbreaking methods we have introduced…

Essentially, Hotz’s method is more like unlocking rather than jailbreaking the 1.1.3, however, the catch is that it requires you to modify your iPhone’s baseband and is more suited for advanced users. There is also a risk of bricking your iPhone, because this method is so prone to error if you’re not certain about what you’re doing.

I suppose the main advantage is that this method works for both Windows and Mac. If you’re interested, click here to visit the Hackint0sh Forum for the latest intructions and news.

Though the forum says 1.1.2, it’s been proven that it also works for iPhones 1.1.3!
