My colleague at work bought his iPhone at DigiWorld - 16 Hang Bai St. Hoan Kiem District, Tel # 04-9364333. They have unlocking service. The phone is made in the US with original SIM from provider. They unlocked the phone afterwards.
Word of advise: Unlocking service is thru software application ONLY , and NO hardware changes. So, when you have your phone serviced, say you just want your phone unlocked thru software. NEVER allow them to open your iPhone.
Remember: You are doing this at your risk.
