It may be more of a stumble than a full-on trip, but Microsoft is having a bit more technical trouble with its Windows Phone 7 update.

Microsoft's Michael Stroh, who writes for the Windows blog, acknowledged yesterday that the company stopped sending updates to Samsung Omnia 7 phones. Those are the same phones that were rendered useless, or "bricked," when Microsoft started to roll out the so-called NoDo update in February.

"The team discovered a technical issue with the update package for this model," Stroh wrote in a reply to questions posted on the Windows Phone blog. His reply was first reported by the WinRumors site.
