Want to groove to the Windows Phone 7 momentum, but do not know just which handset to get with the plethora of models out there? The HTC 7 Mozart might be right up your alley though, and we have just received news that there is a leak for an official ROM upgrade which includes WP7 build 7355-89, and those who have already downloaded it have reported success with the installation process on their Mozarts. Apparently, it will be a clean installation, removing any carrier-specific branding which might have been there prior. Of course, the largest component of NoDo would be the inclusion of the long awaited copy-and-paste functionality – making us wonder why that wasn’t included right from the beginning. You given it a go yet?
