I have an iPhone 4 on Verizon with unlimited internet. Because of this and the lack of home internet i tether my iPhone 4's 3G to my iPad and macbook pro all the time. Specifically to the tune of 30GBs a month. I want to take advantage of the best buy free upgrade to iPhone 5 but i don't want to lose my unlimited data, which i tether jailbrokenly with tetherme. Aside from buying an iPhone 5 outright do you think theres a way to upgrade with best buy and still keep my unlimited data?
