Add Sony Ericsson to the growing list of potential Windows Phone 7 device rumors. There are plenty of rumors surrounding HTC devices and now Sony is rumored to have the Julie.

The Julie is reported to have a 4" screen and sliding QWERTY keyboard along with the standard WP7 goodies (1 gigahertz processor, multi-touch capability, etc).

Sony was mentioned amongst the many hardware launch partner when Windows Mobile 7 was announced during the 2010 Mobile World Congress.  So the rumors aren't that far of a reach except Sony hasn't been a major player on the Windows Phone front.  Maybe things are about to change.

Still, it would be interesting to see a Sony WP7 phone with Xbox integration. I wonder how the Play Station crowd will react.
