而且如果北美手機這麼便宜，為什麼一堆人還是堅持從台灣帶手機來北美用?
像我的 Diamond2 和我朋友的 Cruise、Diamond 也都是從台灣帶來的
還有一堆用 SE、iPhone、Nokia、日系手機的人也是
誇張的是，朋友從台灣買的 iPhone 竟然在這邊不能上 3G
因為 Rogers 有鎖 IMEI，只要不是 Rogers 賣的 iPhone 都不能用 Rogers 的 3G 網路
Most Asia countries use 1900/2100 for 3G data. While carries in US use UMTS 850/1900 (At&t), or 1700/2100 (t-mobile), ...etc. That's why we have very limited choice for 3G phone. (And I have to stick with Sony X1"a" with At&T)
