I recently posted this question on phandroid, but i also wanted to get some feedback here. I asked: So, I am fairly new to the Android world and longing to replace my iPhone with a well made Android device. This may sound like a noob thing to ask, but is it possible given the
Any unlocked GSM android device would work on AT&T's network, however, there are only two devices in the wild that you would get AT&T 3G with. They are both from the Canadian carrier Rodgers. The devices are the HTC Dream and HTC Magic and would be Rodgers branded. You might be able to find something on ebay just make sure to look for the Rodgers versions. If you do not buy one unlocked, you will have to have it unlocked for it to work on AT&T.
Thank you for the response, I am pretty much holding out on the Xperia X3 Android device.

I maintain a rather extensive list of PDA phones, and while searching for an Android device that would work on AT&T's 3G frequency, I found on eBay some versions of the HTC Hero and Samsung Galaxy that did list 1900MHz among the 3G frequencies. While these phones do officially exist (HTC Hero 130 and Samsung Galaxy I7500L), make sure to double check with the seller. By the way, the Sony Rachael/Xperia X3 does not appear to support UMTS 1900.
