currently only wifi.
Correct but I'm curious to if it is simply something they can "turn on" as an example almost all cell phones used to be GPS enabled but the GPS feature was inactive unless you paid for it.
Just bought a 16 gb iPad with retina display and currently only wifi. If at some point I wanted to ad cellular data and be able to run it through my carrier is that possible or would I need to purchase a whole new iPad?
Only for iMessage though correct?
