Nokia’s diagnostics app secretly contains CDMA, AT&T LTE test screens

slightly detective work can certainly go a ways. Some little-known sections of Nokia’s Windows Phone diagnostics app were found by Nanapho because it analyzed its XAP file, lending credence to rumors that AT&T-branded Lumia phones are being tested in the present day time. The location uncovered screens facing “LTE TX” and “LTE Band Lock,” with the latter adding references to Band 4 and Band 17 — AT&T-specific radios. The last interesting piece of evidence was dug up inside the MMS settings tool, which offers code that refers to CDMA. We’ve heard past rumors suggesting Verizon will be getting a Lumia in addition, but there have been no indications that LTE Band 13 is in testing here; Big Red is reportedly hesitant to launch new Windows Phones without 4G connectivity now, so choosing to move without it should suggest the carrier is willing to make a couple of compromises within the hopes of adding the Lumia to its ranks. Hopefully we’ll find more clues within the days leading as much as CES.
