how to setting modem sierra 881 u

Hi everyone,

I'm almost at breaking point and hoping very much that someone can help me...please!

I'm trying to set up my Blackberry Bold 9000 as a tethered modem to get mobile internet on my mac through my phone. I'm on an 02 contract with a data bundle.

Here's what I've done so far:

Set my BlackBerry to discoverable and paired it successfully with my Mac (bluetooth on my mac is turned on) after watching the video at vimeo.com/963933.

In the Bluetooth Mobile Phone Setup screen in the Bluetooth Setup Assistant, what I don't have is the Username, Password and Phone Number. I may have them but don't know which UN, PW and phone number I'm supposed to enter.

I'm running Leopard Version 10.5.6.

I'd be happy to connect my BlackBerry to my mac by USB if that makes things easier.

Any help would be fantastic!!!

Thank you all
