I'm a new ATT customer and just got the I4, I was bummed about the 2gig data limit. My gf(not on my plan) who also has ATT and has the unlimited is willing to give me her unlimited. Is it possible to do this? Has anyone tried. I am think I we can merge the accounts, I can then have my number ported to her sim and Voila! I now have unlimited. Is this feasible?
