Windows Phone 7 users, the moment you’ve all been waiting for has finally arrived. After fits and starts, Microsoft is finally beginning the wide-scale rollout of its first major update to the mobile platform, including the ability to copy/paste, startup and shutdown speed improvements, faster app access to phone memory so your apps launch faster, and more. The update, called “NoDo,” has already begin hitting some WP7 phones, according to a post at WinRumors. Un-branded Windows Phones will get the update first, and while Microsoft says they’ve released the update to wireless carriers to push to carrier-branded phones, it’s up to them to release or block the update from their users. Unfortunately, that means that most North American WP7 owners will have to wait until their carrier pushes the update down to them. The update also includes some improvements to phone performance over Wi-Fi, updates to the on-board Outlook client, and an update to the Windows Phone Marketplace so users can more easily search for and find the apps they want to install. Considering some of the previous issues carriers have had with Windows Phone 7 updates, it would make sense if they’re a little hesitant to open the floodgates, but with WP7 owners clamoring for it, it’s just a matter of time.
