Owners of the Dell Venue Pro and the HTC HD7 should be seeing the Windows Phone 7 “NoDo” update hit their handsets soon. According to the spreadsheet Microsoft posted to track updates, the company has started sending the update to those handsets.

Microsoft has seen considerable customer backlash for NoDo delays. The update was originally scheduled to arrive the first week of March, and was then pushed back to the second half of the month. Microsoft apologized for the update delays in a blog post from spokesman Eric Hautala:

I know many of you are disappointed, even angry. You certainly have a right to be. We’ve fallen far short of your expectations, and our own, and for that I’m truly sorry. We didn’t set out to let you down. But it’s clear we did. Whether you’re someone who has followed our progress from the start, or are new to Windows Phone, you deserve the updates we’ve promised.My job is to get us on the right path and deliver them.

Hautala, whose official title is “General Manager, Customer Experience Engineering,” also said that some users may get two updates for their phones — the February update that caused problems with some handsets and the latest update. He said that those updates could arrive days or even a week or two apart.
