Well, if you are iPhoneVietnam Mobile Professional, this is definitely a sad day indeed. The iPhone Dev Team just released iUnlock which allows anyone to unlock their iPhones with a graphics user interface easily from their computer for FREE. In Saigon, that means you no longer have to pay $100 to unlock your iPhone at iPhoneVietnam. And yes, you can use your Viettel, Mobifone, and Vinaphone sim cards.
I can’t wait to get my next iPhone (last Sunday I gave my 4GB iPhone to another friend).

Go here to unlock your iPhone in Saigon:
TNHH Tan A Long
76 Bui Vien (Pham Ngu Lao Area), District 1, HCMC

You can use the iPhone as a phone in Viet Nam, but can you get any data services?
