So I’ve been an iPhone user since day one.  I have a good anount “invested” in the Apple/iTunes ecosystem but I’m grown tired of the iPhone/AT&T.  I’ve ordered an iPad 3g to take of my major mobile data needs so wouldn’t mind finding a cheaper phone/plan.  I like the Google Nexus but need convincing/help on the cheapest provider and solutions to allow me to keep my iTunes investment useable.
