All your cell phone needs in order to transfer files back and forth from your computer with ease is bluetooth. If you are looking for a phone that will let you transfer things like pictures and ring tones, look for a bluetooth cell phone. Bluetooth is a such a common feature now that it should be available with almost every phone on the market, including many options that are usually free with your cell phone plan. If your computer doesn't have bluetooth installed, you can find a USB bluetooth dongle for very little money at most computer stores that will work fine.
