No data cable for the 3650.

Your options: Get infrared (IrDA) or Bluetooth for your PC.

For some things, a PC based (USB) MMC card reader is also useful.

Doesn't matter. There is no place on the phone where to plug in a cable (serial or USB) for PC Suite. The component is shared with many PC Suite versions for different phone models and such options will work with phones that have cable connectivity.
