I have found instructions for jailbreaking and unlocking 3.0 firmware for a Iphone 3G, is this the same as unlocking 3.0 firmware on a 2G Iphone? I am new to the Iphone world, and am looking to jailbreak and unlock for Tmobile.
My bad, instead of blacksn0w, you would need "BootNeuter".
All apologies for the confusion.
