How to tether a Blackberry Curve 8310 on the AT&T network

AT&T has a pretty good guide for this here. You can also go here for more information. Really, all you should need to do is install the Blackberry Desktop Manager software from the CD that came with your phone, or from Blackberry's website, and also install AT&T Communication Manager. The Blackberry Desktop software installs the device drivers for the phone, and AT&T Communication Manager works to setup the device as a modem. Then just launch AT&T Communication Manager and click Connect, and away you go with Internet access through your Blackberry.

Make sure your plan is setup to have tethering access, which is typically about $15 more a month. Without it you may still get this to work for a while, but you'll end up with a surprise in a bill at some point and are better off just shelling out the extra $15.

If you somehow found this page and are looking for tethering software for the Verizon network, download the VZ Access Manager from vzam.net. That is what Verizon uses for tethering. Again, make sure you call Verizon and set yourself up with a tethering plan first.
