In an exciting networked world we are living in, just about everything can be connected to anything. By all means that includes your mobile phone, at least if it is not more than a couple of years old. You can connect your mobile phone to your computer via bluetooth, or more commonly via USB, in which case it will also re-charge itself. Depending on your phone once it detects it has been connected to an USB port, it will offer to enter one of the two modes; a file transfer mode and a phone mode.
A file transfer mode will mount your phone to your desktop as if it was a disk (like an USB stick) and then you can move files back and forth between your hard disk and your phone (like putting a cool music file to use as your ring tone). However, what we will be focusing on here is the phone mode, which is quite interesting, because it allows you to, by using appropriate software, synchronize your phone and control it using your computer.
