The next big Windows Phone 7 update 'NoDo' (build 7355) has just leaked to the web. Although the leak is a non-final version of NoDo, and is only available to HTC 7 Mozart devices, it's still a leak ahead of the final build, which is actually due tomorrow.
Many are claiming the issues may push back the release of the Windows Phone 7 major update "NoDo" which brings Copy & Paste support, better performance, the compass API and better marketplace search to the platform, but we're still confident the update will go ahead on March 8 for many WP7 owners.
The leaked Mozart firmware build 7355 isn't the final release of the Windows Phone 7 NoDo update, which is expected to have a build number of 7389. Since this is a non-final build, we encourage users to simply wait for the final and official release from Microsoft before proceeding with the update.
Mobiletechworld reports that the ROM version is RUU_Mozart_HTC_Europe_1.30.401.01_5.54.09.21_22.33 b.50_RELEASE. The site also reports that the Samsung Omnia 7 is also expected to leak very shortly (firmware KA1), but because the official release should surface tomorrow, it's best to wait.
Update: Turns out, this is the actual RTM and not build 7355 as previously reported. The leak is build 7389.
