  Nokia Lumia 720 + Amber  Good news for those with the awesome
Nokia Lumia 720, as the 1334 Amber firmware and 10328 OS update
(GDR2) is now sitting on Nokia’s servers.  If you're adventurous
and use Nokia Care Suite or Navifirm+, you can download the ROM
and manually flash your device (losing all information in the
process); alternatively, you can wait until your carrier begins
to roll it out over-the-air, which is what we recommend.  Nokia
Lumia 720 + Amber Manually flashing a Lumia 720 with Amber
update  Nokia’s Amber update for the Lumia 720 (and the 620 and
520) have been slower to be released when compared to the high-
end Lumias, though Nokia has promised that all devices should be
updated by the end of September. Lots of people have been
looking forward to the Lumia 720 update as that device is quite
popular. With the new files on Nokia’s servers, it means the OS
build is finalized and it should be rolling out to the various
regions within the next few days.  Nokia Lumia 720 + Amber and
