During that conversation, AT&T informed us they were committed to updating current Windows Phones and were evaluating a post-8107 update aka "Tango" or Consumer Release 3 (CR3). You can read that whole situation here but the important take away was that AT&T users would get a significant OS bump in the coming months (no time frame was committed to).
Now in their help forums, AT&T has once again come out publicly to reiterate this position. From Community Manager Jamileh:
"Hey all - I know you're eagerly awaiting news about this. AT&T plans for a Windows Phone update that will contain the improvements in the 8107 update and more.
I will likely start a new thread as I get more information as this one is getting a bit tricky to find information in.
Again, no time-frame was given. But at least AT&T have twice gone on record on the matter. Now, it's just a matter of waiting which for some of you will be too long no matter how quick AT&T pushes this out.
