Hi, I just got my X8 this week and loving it. One small problem though. When I connect the phone to my laptop via the USB and select file transfer on the phone I can view the SD card in Windows Explorer for a few seconds before the phone reboots. When it comes back on I get a message telling me there is no sim card, the phone locks and Windows Explorer crashes. I then have to remove the cable and the phone reboots and all's fine. Weird! the phone is running 2.1 update 1, the laptop is Vista Home Premium. Anyone else had problems with USB?
