I ran across this in my subscription to the del.icio.us “blackberry” tag RSS feed.
It turns out that while the functionality to use the new BlackBerry 7100t as a Bluetooth GPRS modem has been disabled, you can still use it as a GPRS modem connected via USB cable. This has the added benefit of trickle charging the BlackBerry while it’s plugged into the USB cable, so as long as your laptop has power, you can be connected to the internet as long as you have a cell signal.
To be honest, since I knew that the Bluetooth functionality was disabled, I assumed that all GPRS modem functionality was missing, and never though to try this out. Turns out it’s deceptively simple, and easy to set up. I’ve tried it out, and it works great.
Read on for the details on how to set everything up.
Here are the instructions from the post linked above (written by PDAStreet user bollar:
It turns out that the 7100 can be used on T-Mobile as a GPRS modem for a computer by using the USB cable. Here’s how to configure it:

If these instructions don’t work for you, or could be improved, let me know.
If you have a BlackBerry 7100t, try this out, and let me know how it works!
