1) Will I have a problem activating my phone on Credo (I assume that most ROMs assume you're with Sprint proper)?
2) Once I have managed to activate it, will there be features -- calling, SMS, MMS, etc. -- that won't work?
3) Will I have a problem activating Google Voice (haven't tried on stock yet, but I have a sense of how it should go)?
4) Is there anything else I should know about the Credo / Custom ROM combination that I don't have the good sense to ask here (as a longtime CM user, I've got the basic principles of ROM-flashing down)?
Thanks all, ahead of time, for your answers!
