It all depends on the model of your phone.If you're talking about transferring files, USB leads can be bought to connect your computer & mobile phone.Alternatively, if you phone has Bluetooth compatibilty, you can buy Bluetooth dongles that provide the same function.I find that Bluetooth dongles, while they transfer files slightly slower than USB leads; are a better option, because future phone models are likely to have Bluetooth, while the 'socket' on your phone will be different from any other you have in the future.What type/model of phone do you have?
