Behind the scenes: Unlocking iPhones in Vietnam

As a last step, the technician put the phone back together, and it looked like nothing had been done to it.

However, the phone is now unlocked and can be used with any carrier's SIM. It can also be synced with iTunes and used with the original carrier and it can perform all other functions without any problem. But it is not yet jailbroken, which Tuan Anh will do for free. He will even add lots of applications and utilities at no additional cost.
