That's why the Redmond-based giant has decided to post a "where's my phone update" page (check the source link) on its official site, and according to it, T-Mo is "scheduling" the Dell Venue Pro's and the HTC HD7's updates. Apparently, this scheduling thing lasts 10 days or less, so we can expect it pretty soon - or at least we hope so.
Things look a bit grimmer for the owners of AT&T WP handsets. According to Microsoft, the carrier is still testing the update on its phones or, to put it less delicately - no one knows when NoDo will reach the HTC Surround, the Samsung Focus and the LG Quantum.
Microsoft is planning to update this page once a week, so you can check it from time to time - who knows, some good news may be coming (at last).
