Nokia has finalized the Tango ROM + firmware for the AT&T Lumia 900
We’re in the finally stages of waiting for AT&T and Nokia to push out the much anticipated ‘Tango’ update for the Lumia 900 Windows Phone. Windows Phone ‘Tango’ will feature improvements to MMS including multiple messages and audio file support in addition to other minor changes. In addition, the inclusion of new firmware from Nokia should allow some of Nokia’s exclusive apps like Counters and Contact Share to finally work as well as flip-to-silence and other bug fixes and enhancements.
The information comes via Navifirm+ which shows uploaded files to Nokia servers. There we can clearly see the 8779 update (slightly higher than the 8773 OS on some Windows Phones) with the AT&T naming in the files.
