Quick Treo delights - Bluetooth DUN

Suddenly realized that I had not mentioned any new delights, courtesy of my Treo650. In the true Treonaut spirit, I won't disappoint. While I was in LA for CSUN, had the opportunity to try out Bluetooth DUN. Please advised that DUN networking via cell phones is nothing extraordinary, but it does come in quite handy.
Essentially your smartphone becomes a wireless dial-up modem, which delivers data over the EDGE network at speeds 56kbps - 110kbps. Not lightening fast, but it can help you avoid the cost and potential security hazards associated with hotel provided Wi-Fi access.

I have an 'all-you-can-eat' Cingular wireless plan, so there is no hard-set limit of how much data I can transfer via DUN. Pretty slick.

My first experience with DUN was via Futuredial software on a very basic Samsung SPH clamshell style phone. Using that sort of setup, you had to rely on vendor software and cables purchased from Radio Shack. Bluetooth DUN delivers the same features, but without all of the wires.

Before trying this with the Treo650, you'll need to flash your firmware to latest version. To be clear, there are different firmware versions available, so be sure to get the correct software. I have an unlocked GSM smartphone, so I grabbed this one.

The instructions are very intuitive and you'll need to back-up your data ;)
After you've flashed the firmware and followed the instruction for setting up DUN, you'll need to pair your notebook or other bluetooth enabled device to recognize the Treo650.

My notebook did not have native bluetooth, so I simply plugged in a USB bluetooth adapter.
Everything worked quite well.
