AT&T to start unlocking off-contract iPhones this Sunday April 8th
Until now, in the US at least, the only way to unlock an iPhone which was not factory unlocked is to use a software unlock(Ultrasn0w) or a hardware unlock(Gevey Ultra SIM) so that you can use your GSM iPhone with any GSM carrier of your choosing.
Engadget has reported that an AT&T spokersperson confirmed a policy change regarding iPhones that is set to start this Sunday, April 8th(Easter). According to an anonymous source, this change in policy will be that AT&T will begin offering to unlock iPhones which are not under contract for use on other GSM service providers.
This is great news for AT&T customers who have an iPhone out of contract and would like to switch to a different provider. So far, it seems as though AT&T will be the only company unlocking off-contract iPhones, but we can hope that the other major providers will begin to follow suit, especially Sprint and Verizon who carry the iPhone4S which is a world phone and can be used on both CDMA and GSM networks.
