I have been using iSyncr to sync my Nexus One to iTunes. It usually works fine, albeit verrrry slowly (takes 4 hours to do the initial sync of about 2500 songs/16GB). Today, I set it syncing and my Nexus One mysteriously took itself out of USB mode. I hadn't touched anything - my phone's display just suddenly went from the orange Android saying "USB Storage in Use" to the green Android saying "tap here to access files over usb from a PC" or something to that effect. It seems to happen only while iSyncr is syncing. Any ideas? I like iSyncr but if this keeps up, it won't be useful. Thanks!
