Sony Ericsson was named a Windows Phone 7 partner a year ago, but — like another we could name — seemingly scrapped plans to produce a device and chose another OS instead. Or did it? Pictures of what looks to be a Sony Ericsson prototype running Windows Phone 7 recently surfaced at Lizhecomb , and it could be that SE’s looking to try again… but probably not. You see, rumor had it that Sony Ericsson did produce a prototype sliding WP7 handset — the Julie — much like the one above, and this one certainly looks a little prototypical compared to contemporary designs. What it may add up to is Sony Ericsson and ASUS in the same boat — two WP7 launch partners that failed to launch, but each with hardware to show for it.
