Windows Phone 7 is slated to hit Europe next month according to most of the rumormongers out there, and Microsoft has confirmed via a press release that the five biggest U.K. mobile carriers will all be stocking Windows Phone 7 devices by the end of this year.

Vodafone, O2, T-Mobile, Orange, and Three are all on the WP7 bandwagon, although we are still searching for a specific launch date to look forward to. At least those in the U.K. won't have to consider a network swap if they want to get their hands on one of these devices.
