請問AT&T 3G是使用什麼規格?
是WCDMA還是CDMA之類的?
我找到這個網頁提到 At&T 的網路系統與一般速度:

It's fast among other Qualcomm CPU device (of course, hard to beat any phone w/ Intel Xscale CPU). It got a lot of ram to run memory hog program like TF3D and Igo8. The only concern is the famous case cracking issue. I had mine sent back to SE to fix after 3 months of use (could be caused by opening the case a lot due to rom cooking).
So after all how do you like your X1? Any warning/advice you'd share to people who are looking at this phone? If you were given the chance to pick up another phone, would you still pick that?

WCDMA,跟其他地區一樣,只是頻率不一樣,美國 AT&T 是用 850Mhz, Tmobile 是 1700Mhz
但其他地區如果沒記錯,大部分是歐規的 900/2100Mhz
