You can synchronise your phone with a PC using a USB cable, Bluetooth™ or Infrared (IR), depending on your phone model. The USB cable is recommended because it's faster when you're transferring a large amount of data, whereas Bluetooth™ and IR can be used to transfer data wirelessly.
Most problems you experience while synchronising usually occur when the computer and the phone do not connect properly.
Note: Too synchronise your phone with a PC, you must install Sony Ericsson PC Suite on the computer.
