[Mobile World Congress] Despite the recent “merge” between CyberShot and Walkman into the Sony Ericsson IDOU phone, the company is still making interesting one-trick pony phones (meaning they one strong point, like “photos” or “music”). The Sony Ericsson C903 is a simple camera phone that is good at what it does. Activating the camera is easy and you can record decent-quality video and fair quality photos. The phone also has Assisted GPS, that can be used to geo-tag your photos (remember where they were taken) or help you find your way. The first photos of the C903 appeared about a week ago, and that’s the first time that we have been able to use it.
