Redsnow+Ultrasnow= iPhone 3GS unlock
Yes its true, the iPhone Dev Team confirmed that the iPhone 3GS is unlock-able with the same tool ultrasnow.
According to the iPhone Dev Team:
" And yes, ultrasn0w will be able to be used on the iPhone 3GS for you unlockers! (In fact, without any modifications whatsoever!)"
That means we can use the same tool, redsnow and ultrasnow to jailbreak and unlock the iPhone 3GS. so for you guys who
owns iPhone 3G and 3GS, just follow the instruction below on how to unlock your iPhone.
And just like with the 3G, ultrasn0w for 3GS requires that you do not update your baseband when Apple comes out with new firmware.
