Hi ppl, I was talking to a friend in Taiwan. He said that his friend bought a iPhone 3G in Hong Kong and brought it back to Taiwan. Inserted the Taiwan sim card without unlocking it (or maybe it was unlocked already when he bought it in HK) and was able to make calls like normal. I've also read some forum posts in a Taiwan forum and people are also discussing they are using the iPhone 3G. Is this possible? I've read the posts here and I don't think the "unlock" is available for the 3G yet? Here is a post in a Taiwan forum (in Chinese): http://iphone4.tw/forums/showthread.php?t=13502 Thanks in advance.
