Microsoft begins pushing out Windows Phone 7 security update

Microsoft has begun notifying some Windows Phone 7 users that a new security-focused update for Windows Phone 7 is ready for download.

As MobileTechWorld.com first reported, the "7932" update is being delivered to users, as of May 3. It includes updates to a previously disclosed issue with fradulent third-party digital certificates from Comodo.

Microsoft has revised its security advisory on this issue, noting that the update is beginning to go out to users as of today.

According to the frequently-asked-questions section of the advisory, Windows Phone 7 "customers will receive an on-device notification once the update is available for their phone...will have to connect their phone to a computer and use the Zune PC client or Windows Phone 7 Connector (for Mac) to complete the update process."

Users who don't already have the February and/or NoDo copy-and-paste updates on their Windows Phone 7 devices will get these updates when they get the 7932 update.

"Windows Phone updates are cumulative. When you install the latest update, you’ll also get any previously released update if it’s not already on the device," said a Microsoft spokesperson.

I asked the spokesperson how long Microsoft estimated the rollout process for the latest update might take, given company still has not completed the rollout of the first two updates for all Windows Phone 7 users, due to delays in carrier testing. The spokesperson did not respond to my question.
