"So while it might not sound exciting, it's still important because it's paving the way for all future goodie-filled updates to your phone, such as copy and paste or improved Marketplace search," Stroh said.
However, Microsoft has now issued a statement confirming it is aware the update has jammed some phones and is "looking into these reports".
Windows Phone 7 users update their phones by using either the Zune software for Windows OSes or the Windows Phone 7 Connector for Mac using a USB cable, Stroh wrote. Both of those programs, however, may need updating before the new update is installed, he wrote.
"We're very sorry for the inconvenience," Microsoft responded on its support Twitter feed. "For this issue we would suggest taking it to a store."
