It appears that AT&T will soon begin to deploy the March Windows Phone 7 update (also known as NoDo) to Windows Phone devices it carries. A leaked internal memo obtained by WinRumors.com indicates that updates will begin for existing LG Quantum and Samsung Focus users on April 19th. Unfortunately, HTC Surround customers will only see the update starting in mid-May. In more detail the memo outlines the following:
Microsoft is planning to release two new Maintenance Release (7008 & 7390) updates that require a three-phase installation. The update installation process includes:
- Installing Zune software
- Installing the 1st (7008) MR which prepares the WP7 device to accept the enhanced (7309 [sic] “NoDo”) update
- Installing the 2nd (7390 “NoDo”) MR update that adds new device functionality
Customers will receive a notification starting on 4/19 advising them of an available update for their phone. Once the customer completes the 7008 update, they will be able to immediately update their devices to 7390 (NoDo) by disconnecting and re-tethering their phone to their PC. If the customer does not immediately update their device to 7390 (NoDo), they will receive a notification that an update is available within three days.
The memo is supported by the fact that Microsoft’s own deployment timetable has now been updated for the LG Quantum and Samsung Focus to “Scheduling” from “Testing.”
