IMHO this is the best looking 7100; even better than the rumored 7100g. I'm in London until mid-February, so I called O2 business sales out of curiousity. I'm told that I should be able to order phone parts through their department, but the phone hasn't been released yet. It might be available next week so I'll wait a bit and give it another shot. For anyone interested, the O2 business sales line is 0800 089 0250 or 08457 525 252. That might work from the US by dialing 011 44 845 752 5252. I own an unlocked 7100t and use it regularly in the US and UK. The plastics should simply swap out.
No, I'm referring to the "guts" of the 7100 series. All of these 7100 variants likely use the same PCB, LCD and button placement. The "look" comes from the casing itself. Nokia was famous for doing this with their older phones in different markets; IE GSM version could be housed in CDMA version plastics.
the bulk of it would be i would assume, you could afterall load the software onto it... but im not sure if the speakers/receivers and buttons are easily detachable and where you would purchase a keypad... and as i think of it, where would you get the plastic casing too?
