Sprint most likely won't activate a phone not made for Sprint. It's possible to activate the phone for use as a phone, but for data, it will try to connect to Verizon, Alltel, or any other CDMA carrier that already has the Razr V3C. As it stands, Sprint doesn't offer a single phone by Motorola on their service (not counting Nextel). I don't know the reason, but there has to be a reason Sprint won't offer any Motorola phone on their service.
I was wondering... is it possible to use a razr v3c on the sprint network???
I noticed you could buy them cheaper on ebay than the a900.
