Can some one let me know how to unlock HTC Aria phone for AT&T. I called AT&T and they said it cannot be unlocked.
The phone isn't bound by the contract, the service is. Even switching phones and calling them up won't get them to unlock it. I heard of people having this same issue, and AT&T saying it isn't unlockable yet (ridiculous, since the boot screen says "world phone" on it).
I would try calling AT&T up and when they say no, point this out. If that doesn't work, try talking to their supervisor. If you sound really pissed off about it, they may cave and give it to you. If this doesn't work, you can try one of the unlocking services. It'll cost some money, but not too much.
