Nokia Diagnostics app contains secret LTE and CDMA menu has discovered Nokia’s diagnostic app secretly supports tests for LTE and CDMA.

The app contains entries for:
• LTE Band Lock

The LTE Band Lock feature can select the band used by the LTE hardware.  It has ‘Band 4’ and ‘Band 17’ settings which are the ones used by AT&T, suggesting Nokia’s LTE devices may come there first.

The app also has a page for CDMA MMS messaging, suggesting Nokia is also working on support for those carriers.

Nokia is rumoured to be releasing the Nokia Lumia 900 with LTE support for AT&T soon, and this discovery appears to support that rumour.
