Difference between wifi and wifi/4g
I just received an ipad for my birthday!! I have a question, though, regarding the difference between the ipads with just wifi and the ones with wifi/3g. If you have one with just wifi, does that mean you can't get the 3g access if you decide you want it at a later date? The 3G capability is part of the hardware? Thanks! Jeannie 🙂
