作者: fengting0405 如果說買at&t版本的話能用t-mobile的預付卡打電話嗎? Unless your iPhone is unlocked, otherwise you can not use any SIM card other than AT&T.

作者: missahsin SO WHY IPHONE? First of all, there are many WiFi points in the US. I don't need 3G network. And the AT&T don't have unlimited data. I think it's not so cheap. By the way, 加拿大的是unlocked版的嘛?
