I unlocked my phone for Tmobile and was wondering if I hard reset it would I need the 8 digit network unlock code again? Anyone reset their unlocked phone before?

Enjoy

Yes, resetting an unlocked phone can lock it, in at least some cases. I bought a used, unlocked AT&T Samsung Galaxy S II (SGH-I777). Worked fine on T-Mobile for six months, until phone broke and was sent to Samsung for repair. The repair service does a factory reset. My previously-unlocked phone is now locked. Since I've never been an AT&T customer, and don't know who the original purchaser was, AT&T won't deal with me, even though the phone is not under any contract. (Their customer service person explained that they used to do this, but don't any more.)

Hard reset will NOT simlock your phone again.

If above is true, they have sim locked the device again at service centre. This has nothing to do with hard reset.
