My colleague is really tempted after seeing my new phone. The only thing he's unsure of is how this device works on XT. Is anyone using it on XT? Can you get 3G and higher on that network, and what happens in "lesser" coverage areas - does it just step down to 2G or equivalent? Sorry, I'm not up with the jargon so these terms are probably used incorrectly. Hoping someone can clear this up for me.
