A while back TiPb heard something that sounded so outlandish, so beyond the realm of possibility, that we decided not to publish it -- that AT&T's 4G LTE launch hero device could, in fact, be the iPhone. It still sounds outlandish, even though there hasn't been word one about which phone AT&T will launch with, but given the availability of the logical Qualcomm LTE chipset, it still seems beyond the realm of possibility.
But BGR recently caught glimpse of LTE references in a carrier-test build of iOS firmware, and now Engadget has heard that LTE equipment in the 700MHz and AWS frequencies is being installed in major Apple Stores in the US... by AT&T.
I'm not getting my hopes up, nor should you. AT&T could still launch an Android device and Apple could still wait for 2012 for an LTE powered iPhone 6. But as Hans Gruber said in Die Hard, Christmas is the time for miracles.
UPDATE: 9to5Mac says Verizon is also installing LTE equipment at Apple Stores. [9to5Mac]
