During the iPhone press conference earlier we learned something interesting: Apple has Verizon cell sites on its campus. Time to start speculating about just what lovely devices they might be testing with those.
9 to 5 Mac notes that "cell sites, especially ones on private land surely cost a lot, and for Apple to invest in something so expensive they must be putting it to good use." I'd say that testing a CDMA iPhone would be a good use, but it's only speculation and rumors at this point. [9 to 5 Mac]
