HTC One AT&T SIM unlock - Help!!!
I really need help with an AT&T HTC One
The phone is brand new, with the factory AT&T ROM (1.26.502.12).
I bought a SIM unlock code from 3 sites (cellunlocker.net, 2 ebay vendors) but they all gave me the same code which does not work.
Is there any other way to unlock via software? I already did S-OFF with Revone.
