Really? Spam? I kind of doubt it, unless everyone was buying penny stocks, loan refinances, and tummy tuck devices. My two Cyber Monday purchases were both driven by email marketing, but neither one was "spam".
Beacause I don't relish the thought of shelling out over $900 (unlocked iPhone 6, 128 GB, $850 + 8% tax) any sooner than I have to. Even if I got one subsidized, it would still be about $500. This isn't pocket change.
"there's nothing that would stop you from buying a Verizon, AT&T, or Sprint device at the Apple Store and coming over and putting a T-Mobile SIM in it,"
Umm, except for the fact that AT&T iPhones are SIM-locked for the duration of your contract.
