iSync: Use only one connection method per phone
Some phones allow you to sync information with iSync through either USB or Bluetooth. When you set up your phone, you'll need to select which method to use in iSync.
Please be aware that you cannot switch back and forth between USB and Bluetooth when syncing your phone. iSync will only use the method you selected during set-up to establish a connection to your phone.
If you later change your mind and want to use the other connection type, you must remove the phone from iSync, then add it again and select the connection method you prefer.
