im currently tethering with verizon for 30 dollars a month. been looking at tetherberry, but recently read about tethering through bb desktop manager. read that u can configure ip somehow to teather for free. is this possible?
Yes it is. I've done it with mine. You have to have desktop manager 5.0+ I believe. Connect your blackberry, open up dm. Click ip modem. click configure and go through setup. After, click connect to internet and you should be ready. Leave dm open though. It should say how much kb you've used.

they will know how much data you are using but they will think the data you are using is on your blackberry.. not anything about it being tethered to a computer.
