Sadly, the iPod, iPhone, Zune and Windows Mobile aren't supported yet, but the rest of the device list is pretty decent: it includes the BlackBerry Pearl, Storm, and Curve, the G1, Sony Ericsson Cybershot and Walkman phones, the Kindle, Nokia N and E-series phones, and most digital cameras and flash-based camcorders.
Initially the system will allow file-sharing with Sony's PSP games console, Nokia's N-series mobile, Sony Ericsson's Walkman and Cybershot handsets and Microsoft's Windows Mobile smartphones.
