Hey guys, I am new on this so don't have much experience, Is it possible to unlock an iphone4 firmware=4.2.1 baseband=3.10.1. from AT&T. Could I downgrade the firmware/baseband ? I have seen many websites promoting it don't know if it's legit.

Thamks in advance.

You COULD upgrade your baseband to 6.15.00 and unlock but then you could never restore to stock firmware until the firmware contains a baseband that is equal to or greater than 6.15.00, which is a LOOONG time away for iPhone 4 users, considering that you are at 3.10.01 right now.

The 6.15.00 baseband is NOT for iPhone 4, but only for 3G and 3GS.
