可以阿! All you need to do is call Tmobile and request for an unlock code! BTW no matter if it's AT&T or Tmobile or any other carrier in US. All the phone thet have are locked.... So you need to unlock it first before use it with other carrier.
可是 DHD 有新的 Sense... MyTouch 4G 其實超快的! 我同學也有一隻...... 本來想換的 可是他機身有 T-Mobile 的圖案就覺得很討厭..... I hate the T-Mobile tag on the phone...so still stick with my Nexus One....
