I just discovered yet another mobile tech news site Mobile360.com, which launched around May of last year. It's London based and appears to share ownership with the well established German language site mobile360.de.
General mobile news is a crowded and competitive world but Mobile360 seems to have hit the ground running with frequent updates, well researched and well written items and an attractive site design. They apparently have some journalistic chops too. I discovered Mobile360 because they were the first to break the story that Nokia's Navtech was shutting down their developer program with only a few days notice to their partners.
