If you're going to use it as a wifi hotspot it's pretty simple.
Verizon = 3g
Verizon = Gossip of download caps.
Verizon = Doesn't have 2.2 or bootloader unlocked so no native Wifi Hotspot. Hot spot only by application and thus no VOICE + Data
Sprint = 4g in your neighborhood in December
Sprint = Definitely no caps on 4g data for the foreseeable future.
Sprint = 2.2 and unlocked bootloader so you can have native wifi Hotspot.
Sprint = EVO w/ 2.2 offers Data tethering + voice at the same time.
Sprint is a no brainer.
