I read in a forum that the correct UIDs for generic UIQ 2.1 platform, P800/P900 and P900-only are as below: (0x101F61CE), 2, 1, 0, {"UIQ21ProductID"} (0x101F80BE), 1, 0, 0, {"SonyEricssonP80xPlatformProductID"} (0x101FBB35), 1, 0, 0, {"SonyEricssonP90xPlatformProductID"} I do not know the exact source for this information (I didn't find about it in the Sony Ericsson site pages), but I will update the uiqsdk accordingly. alf
