Over the past two years, I've been hosting the Network World Wireless & Mobility Technology Tour (the latest tour finished just last week in Denver and Boston). The tour's keynote speaker, Craig Mathias of the Farpoint Group, always asks the audience whether they are using Bluetooth. A smattering of hands go up in the air, and then he asks them if they are using Bluetooth for something other than a wireless headset for their phones. Most of the hands go down.

If you are serious about using Bluetooth for something other than a headset, head to the Mobile Action Web site (http://global.mobileaction.com/product/product_Bluetooth.jsp) to read up on its new Handset Manager MA-720, a Bluetooth data suite that aims to link cellular phones with PCs. The latest versions adds more device access and improves data transfer speeds, as well as provide a single platform for all Bluetooth-enabled Mobile Action Handset Manager models, the company says.

The $54.95 MA-720 comes with an ivory white Bluetooth dongle and accompanying software that matches a user's cellular handset. The software (Handset Manager Version 9.0) supports 20 languages and more than 80 GSM, CDMA and 3G phone models (go to http://www.mobileaction.com for a complete list and the latest software versions). The system supports any PC's Bluetooth Human Input Devices (HID), including keyboards and mice, Mobile Action says. The new version now supports wireless applications and devices such as MSN Messenger and Skype, and the dongle driver supports Windows XP Service Pack 2.

But connecting to a PC is just the beginning of the software - it has a phone book editor that lets you edit, back up and organize your contacts list on a PC and upload it via Bluetooth to the phone; a calendar synchronization application; a picture editor that lets you compose and edit pictures and GIF clips into animations; an MP3 clipper that lets you clip parts of an MP3 file in order to create MP3 ring tones; and an audio composer that lets you edit personal polyphonic ring tones with up to 128 different instruments.
