The three standard methods to connect your computer to GPRS mobile phone are:
Infrared - available on most business mobile phones - just align the IR. port on the phone with the IR. port on the Laptop.
Data-cable - reliable and doesn't require the careful alignment of IR. which may be difficult when traveling
Bluetooth - My preferred solution - often difficult to set up but once its configured Bluetooth provides a very convenient connection. Bluetooth is available for connecting to Laptops via USB, PC-cards or CF-cards in addition to cards for PDAs such as those offered by PALM. Older Compaq IPAQs will require an expansion jacket but newer Pocket PC devices usually include a suitable expansion port (check at the time of purchase). One very important point is that Bluetooth devices are very low powered so do not drain your computer battery or phone battery too much. Many people will be tempted by the all-in-one phone/PDA, but consider will you be happy with the relatively short battery life, large size and weight and unreliability of many PocketPC devices.

The 1680 has no user connectivity via USB. The USB port present is only for use by service personnel.
