Late last month, Microsoft began rolling out a pre-update update to Windows Phone 7 devices to prep them for the upcoming NoDo upgrade. Unfortunately, around 10 percent of WP7 users had some issues with the new software, forcing Microsoft to yank it until everything was sorted out. All of the kinks have been worked out, though, and now Microsoft has continued to push the update out to WP7 devices in preparation of the big copy/paste upgrade.
Microsoft's NoDo update is set to come out within the next week or two, and will bring with it several enhancements and new features for WP7 owners to enjoy. There's no word on if these problems will delay NoDo's arrival, but I'm sure Microsoft wants to get WP7's first major update to users as quickly as possible, so don't be surprised if it arrives on schedule within the next week or so. We'll keep you updated.
