The last set of Windows Phone Updates that were pending at at&t, the ones meant to be released for the HTC Surround are not being scheduled to be released. "Scheduled" is the step that happens right after testing finishes and before the updates are released to the users. This step can take up to 10 days, but in the last few updates from at&t they only took one or two days. If you are running an HTC Surround, you should receive the notification of an update being available in a couple of days. Everyone with this smartphone should expect to be completely updated in 10-15 days at the very latest (according to our estimates).
To recap, at&t and the manufacturers had decided to stop the release of the update to this particular model because some changes had been made to the hardware and were not thoroughly tested. This update is the one that completes all pending updates to all Windows Phones out in the US market. Any future phones will be released with these updates already installed and will not require of the February and March updates.
In Europe, Deutsche Telekom and Global and in Australia; Optus who were going through the same steps than at&t, will be also releasing the updates on the same schedule.
While this pretty much closes the update deal in the US, there is still Telstra in Australia who still has not even confirmed any kind of schedule for updating their WP7 phones (shows as still "testing") and Spain’s Telefónica still has no information on their update release which, again still shows them as “testing”.
Let’s hope that the few that are still pending updates get their tests completed as soon as possible
