Tango OS

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.

A lot of hay has been made over Windows Phone "Tango" aka CR3/build 8773 of Microsoft's mobile OS. The update contains a lot of minor things and is mostly focused on compatibility with 256MB devices for emerging markets and low-cost Windows Phones.

Nokia is hard at work with updating their ROMs for all Lumia phones and in fact if you use Navifirm to check, the Lumia 710 and 800 are getting heavily populated with new Tango updates, presumably being readied for roll-out in June.

We grabbed one of those ROM, OS 8773 with firmware 12120 from Mexican carrier Telcel to see what it has on board. Presumably, these changes you see in the above video will also be on the Lumia 800 and 900 ROMs as well, so consider this a sneak peek. Here is what's new:

  • Call forwarding - forward your calls to a designated number for (1) all calls (2) when I don't answer (3) when I am busy (4) when my phone is turned off
  • Call waiting - enable/disable
  • SMS delivery confirmation* - on/off
  • MMS delivery confirmation* - on/off
  • SMS Character set - Reduced (no accents, standard SMS) or Full
  • Send MMS acknowledgement* - on/off
  • Internet Sharing (aka WiFi tethering)
  • Enhanced MMS - Send voice notes, multiple images, video
  • Nokia branded Marketplace icon

As you can see, some of those features are pretty great (especially Internet Sharing) but they're also not necessarily "must have" items either, making Tango a minor update, something we've been emphasizing for some time now. Still, Nokia has done a nice job here and we expect T-Mobile to roll this out sometime in June officially (just a guess).

Some of you may wonder if the OS feels any different (faster, smoother, etc.) and to our eyes, no, it feels exactly the same. Perhaps there are some optimizations here and there but we really didn't notice it. We should also note the MMS issues we had in the video are probably due to this not being a T-Mobile ROM and more over, Nokia pulled their Network app to be fixed  (it'll be back soon) so we can't configure our MMS gateway for T-Mobile.

If you have any questions, ask away in comments. And yes, we'll see about whipping up a tutorial on how loaded Tango on our T-Mobile phone for you 'leet hackrz out there.

Just yesterday we reported that China was destined for some Tango ROM goodness for the Nokia Lumia 710. This was verified by peeking in on Nokia's own servers where they like to toss up the ROMs before they're pushed out (yet another reason to like the company, we suppose).

Tonight, with a quick cache refresh of our NaviFirm software we were able to seen yet another Tango ROM show up, this time destined for Belgium operator Proximus. This ROM has a slightly different firmware as it's labeled 8773.12120 versus the 12111 we saw for China.

We haven't loaded this one up but we feeling a little safer about English being on board. The big question everyone is wondering is Will the bring tethering to the Lumia 710? Our hunch says yes, at least for those carriers who want it.

It was speculated that Nokia did not tie the battery-saver update in the Lumia 800 (and 710) to the tethering feature for fear it could limit adoption by carriers. By separating them, Nokia could get the important battery fix out to the most users while it separately delivers the tethering update.

We imagine we'll find out soon enough. At least it's a good sign that Nokia is pushing out these updates on a wide-scale and we imagine the Lumia 800 will follow soon too.
