As of today, the iPhone Dev team, the same people who released yell0wsn0w...announced their new jailbreak/unlock for iPhone 3g users. its called...Ultrasn0w, and if you are like me, I am jumping with joy(not literally) because I really wanted to use the 3.0 firmware, but the turbo Sim doesn't work with it...but not only can I now use the 3.0 firmware with t-mobile, but they have figured out a way to change the baseband so you can use it with t-mobile!!!!!!!!!!!!!!!!!!!!
it will be released sometime on Friday, on cydia, so you don't even need to use your computer, but I do recommend backing up your iphone before doing this, so you don't lose any apps or music...
oh and iPod touch users, they will also have an iPod touch quickpwn download for the 3.0 jailbreak, and it will be free...so don't go ahead and pay $10 to apple
