Verizon phone SIM in T-Mobile iPad, Update: it works!
UPDATE: I just received my T-Mobile iPad Mini with Retina Display and both SIMs work in it!
Has anyone tried putting a SIM from a Verizon phone into a T-Mobile iPad Air? I'm considering picking up the riPad Mini on T-Mobile for the free 200MB but I want to be able to my Verizon SIM into it if I plan on doing data intensive stuff. (I have unlimited Verizon)
