Using wireless headsets aren't the only things you can do with Bluetooth. There's several "profiles" that can be utilized with the technology. With the knowledge of these profiles, you can discover all sorts of stuff you can do to make life better (disclaimer: unless you have Verizon). However, not every bluetooth phone has all these profiles. For example, some Samsung phones can use the earpiece, but can't transfer files.

1. Transfer files. Forget paying 25 cents to send a multimedia message to another phone right next to you. Instead, use the bluetooth link. Most bluetooth-capable phones, but not all, have a file transfer profile. You can transfer pictures, unlocked ringtones, and even address book entries. PDAs with the file transfer profile can transfer attachments, documents, and other large files. If your computer has bluetooth capability, you can easily transfer stuff to and from your phone as well.

2. Print stuff. Either from your phone or your computer, there are printers out there that can print off your favorite pictures or documents.

3. Keyboard. Tired of the tiny keys on your PDA? Some PDAs will have a bluetooth profile that enables you to use a wireless keyboard instead of trying to smash your fingers on the small buttons.

4. Use your phone as a modem. Crazy as it seems, once you add a full internet tethering package onto your phone account, you can take advantage of the bluetooth link to get internet on your laptop from your phone. This is great if you're travelling a lot for business and don't want to shell out the extra cash for a wireless PC card.

5. Listen to music through wireless speakers. 'Nuff said.

6. Use a GPS Navigation System. Most high-end phones and PDAs enable you to connect a bluetooth GPS receiver to your phone, thus allowing you to have an inexpensive car navigation system.

7. There's plenty of other things that bluetooth can do. Check out this wiki article which shows in detail all of the profiles that are out there.
