I've been using Blackberries to surf the web from my notebook (as tethered modems) for over 3 years yet still very few people know about it. It's never been simple to configure. There are no additional monthly costs outside of your existing Blackberry data plan. Make sure you have a 500 Mb/month plan or greater or it's very pricey.
2 ways to make it work via a USB cable which also charges your battery:
- The old way is complex, details are here but it can be done over Bluetooth or a USB cable.
- The new way is to install Blackberry Desktop 5.0.1 or greater and simply click the IP Modem button but this works only with a USB cable
It works on Rogers Wireless and Bell Mobility. Should work on Telus but I haven't tested it myself.
There's no need for buying software like Tether for Blackberry. I hope this helps a few people save some money.
