Tethering With The 8900 - Success!
 

I hope this info is useful.

I have been able to get the 8900 to tether to my HP Mini netbook, wired and bluetooth.

The speeds are not great, but there is connectivity.

I used this guide to set up the connections:

I wouldn't expect the speeds to be great, it's EDGE after all ;)

I must be doing something wrong. I get error 692 meaning hardware failure. I am using my T-Mobile website as user id and password. Is this correct information to set up?

8900 As a Modem Problem With Set Up.
 

Hi, I am trying to set up the 8900 as a modem, When I get to the step to enter the APN for T-Mobile in the Standard Modem Properties screen, the Change Default Preferences box in the lower right is grayed out so I can not enter the string shown in the steps. I am signed in as the Administrator.
Any ideas how to ungray the box? I am running Vista Home Premium.
Thanks!!

Try going through this FAQ. Using BlackBerry As Modem - BlackBerryFAQ There is Vista specific info there.

has anybody used tetherberry?

For TMO use wap.voicestream.com as the APN and leave the login user and password blank. Also, the dialup number is *99#.

I got it working on the first try with my 8900 Curve via USB connection. The FAQ I used stated that the BlackBerry Device Manager must be running to make a connection.

Hi, The Vista Detail Instructions did the trick. Thanks Everyone for your help with this.
