Apple iPhone 4 (CDMA)
why not android??
thunderbolt is 4g, iphone is 3g
thunderbolt supports simultaneous voice/data (including mms during active call), iphone does not
thunderbolt has better/faster processor
thunderbolt has flashlight (before app download)
thunderbolt has available data tethering, iphone does not
thunderbolt has expandable external memory, iphone does not
thunderbolt has fm radio, iphone does not
thunderbolt has 8+ mp camera, iphone has 5+ mp
iphone has FaceTime, but exclusively to other iPhone 4's, where thunderbolt will have an app to reach other android devices
i know this seems very biased, but i assure you that i am not. it is just a relief to see htc (or anybody for that matter) FINALLY create a phone that dominates the iphone in nearly every category!!
