The theoretical speeds for both networks are faster than my home internet, especially upload. So I was planning to get MyWi and use a 4S as my home internet (or at least attempt to get some form of link aggregation going). My main dilemma as AT&T's speed versus Sprint's unlimited data. Then again, AT&T's 2GBs or 4GBs might be enoughI'm using as much as 35GBs on some days, but I don't know if that would change if I sparingly use the phone or use link aggregation. I live in Rhode Island, where network coverage in general is about 3 or 4 bars. So I need convincing as to whether I should go with AT&T or Sprint. And please not one-word responses; some rationale would be nice. Also, does either network count incoming calls against plan minutes? Does Sprint offer rollover minutes? I'm thinking of using Google Voice or MagicJack for calling and texting so I can get the cheaper minutes plan (and I would love not to pay for texting).
