Hi everybody. Given all the recent speculation around the timing of our Mango update, I wanted to bring you up to speed on what to expect next.
For months, we and dozens of our partner companies have been laying the groundwork for the Windows Phone 7.5 updateand making solid progress. As a result, we now expect to start rolling it out in the next week or two. At that time, well also refresh the Wheres My Phone Update? table to reflect the worldwide rollout status.
This also seems like a good time to caution against installing unofficial or leaked copies of Windows Phone software.
During the official Windows Phone 7.5 update process, every Windows Phone will also receive software from the handset manufacturer. This matched and paired firmware has been painstakingly tuned so your phoneand appswork with all the new features of Windows Phone 7.5. Since your phone requires the proper firmware to function as designed, my advice is simple: steer clear of bootleg updates and homebrew tools.
By the way, in case you missed it, we recently released new versions of both the Windows Phone 7 Connector for Mac and the Zune software for PCs, which youll need to update your phone. If you havent already, I encourage you to install it. I think youll like the update-related improvements, which speed up the overall update process and give you more control over backups. A small favor: When you update to Zune 4.8, youll be asked to participate in improving the update process. Please consider doing so.
I know youre eager to get your hands on the next release of Windows Phoneand everyone involved with Windows Phone is equally excited and eager to deliver it to you. Please hang onwere almost there.
