Verizon and Vodafone may've already announced exclusive deals for Kin 1 and Kin 2, but a ROM hacker by the name of Conflipper has found provisioning files which detail support for just about every carrier going.
Included on the list are AT&T, T-Mobile, China Mobile and a bunch of European networks, and while it's not enough to go on that I'd suggest T-Mobile-reading customers should wait until the Kin 1 or 2 launches on their network, it perhaps shows future possibilities for other networks.
You can tell I'm hedging hard, and it's true—I wouldn't want to be upsetting any of these kids who have hopes of running a Kin 2 on AT&T. [Conflipper via MobileCrunch]
