WP7: AT&T gets Mango first, September 27th

Finally, the first carrier has broken radio silence on whatever Microsoft is doing with the Windows Phone 7 "Mango" update.

We've seen carriers say it's approved, but no-one would lock in a date. Now, last-to-the-NoDo-party carrier AT&T has come out and announced it's going to be the first carrier sporting the Mango update. WPCentral reports that September 27th is Mango day, and the company will be releasing the update to the following handsets:

HTC Surround (SKU 65212)
LG Quantum (SKU 65205)
Samsung Focus (SKU 65203)

What about the HTC HD7S? Will the Samsung Focus have the same revision issues as with Nodo? Well, it's not all good news. The company said in internal emails that;

"A subsequent release is projected to be available for customers with the HTC HD7S (SKU 65255) in early to mid October. A subsequent advisory will be provided for the HTC HD7S after the MR update has successfully passed TA."

The Samsung Focus will receive a seperate release schedule depending on the revision number. The 1.3 revision will be the first wave, on the 27th, with the other 1.4 revision group having to wait until the end of October. We warned you it was bad news. The information also came from an internal email;

The Samsung team came back an provided this information about WINDOWS 7.5 for the Samsung Focus devices.

rev 1.3(Micron): Windows 7.5 update will be available through Zune on 9/27.

rev 1.4(LSI) : Update has not entered the AT&T SPE lab yet; however, Samsung is targeting for 10/17 lab entry and 10/31 TA

WPCentral didn't disclose their sources but said that they were known and verified, and this lines up with everything we've heard too. We're excited for the release to finally begin, and hopefully other carriers (We're looking at you, Verizon) make some sort of announcement soon.
