I know a lot of people have been having problems connecting their V600s to the Mobile PhoneTools software via Bluetooth. After a lot of messing around, I finally found a way to make it work. Note, you MUST be able to establish a Bluetooth connection to your phone from your computer in order for this to work (e.g. "My Bluetooth Places"). -Install the latest version of the MPT software and run LiveUpdate -Start the software, open the default profile, and cancel out of the connection type screen -When the program opens with the generic phone/skin selected, hit F6 to go into the manual setup -Click the Communication tab and change the modem to the Bluetooth modem, then select the V600 from the device selection screen -After you exit the setup, the skin should change to the V600 and it MIGHT connect to the V600 -If it doesn't, initialize the Dial-up Networking Gateway to the phone via Bluetooth (you can do this through "My Bluetooth Places," or the Bluetooth tray icon) -You will see the BT icon turn green (if you have it set up correctly) and the dial-up networking window will pop up -With the icon still green, refresh the Mobile PhoneTools display (or exit and restart the program, or open and close the setup screen) -It should connect! Now whenever I open the MPT software, I don't even have to initialize the Bluetooth modem. It does it automatically. Let me know if this works for anyone! I hope it was helpful.
