I have tried a 16Gb Kinsgston Datatravel and a 16Gb SD (from eBay, very bad card) that DID NOT WORK on my F700BT, and after the update (wince + unofficial 3.0) they both WORK. I think it´s cos the Wince update. I also tried a 2,5" 100Gb Hard Disk and it works. Anyway, it takes about 1 minute to start playing. Has anyone else tried?
