Needed to use sdptool to check the channel for DUN, and on the Centro it's 2 and change the MAC address of the phone. That's all.

Don't forget to restart bluetooth service, if you had a previous configuration. I wasted some time due to this oversight.

Doing this will drain the batteries on the phone even faster, so unlike my T|X which I could go without recharging for a few days, I need to now diligently recharge my Centro every day.

Now to learn about DateBk6 keyboard shortcuts so I can enter things quicker without needing the stylus.
