I am guessing Boost Mobile/Sprint
Boost doesn't have an Android CDMA yet...just the IDEN one. Virgin Mobile already has an Android Samsung phone. So it's only a matter of time.
Fingers crossed! I have the Boost Blackberry Curve 8530 and love it, but an Android option would be sweet!
I don't know why but for some reason the look of the phone just says Sprint to me. It would be nice for Boost to get something like this though.
I'm going with Verizon, too. Boost Mobile tends to get rejects from Sprint, not new handsets, so a likelier Android for them will be the horrific Sanyo Zio.
