Answer to "How to tell if it's CDMA or GSM version from outside?"Actually there are quite a few different versions of the Touch Pro (HTC Raphael). The Verizon version (Raphael 500) does not have global capability, CDMA only. In addition, the phone has a different exterior than others, a different keyboard layout, as well as 96mb less ram to run applications on the phone whereas all other versions, such as the Sprint (Raphael 800) and AT&T Fuze have 288mb of ram. There's quite a lot of information on these phones at the XDA-Developer's wiki so here's the link: http://bit.ly/bPnhez.
