TetherBerry - Use your BB as a wireless modem for FREE!
TetherBerry, which will officially release their application March 9th has an application that allows you to use your Blackberry as a wireless modem. Some carriers such as Verizon who suck every penny out of you, actually make you pay for this feature on your blackberry. Well, using Tetherberry, there is no need. (After March 9th, you do have to purchase this program) I think this is a great application to use if your carrier makes you pay. OR if you have tried to set up a network connection on your computer and have failed, Tetherberry is VERY easy. A few steps actually. Just download both files, open both applications on your BB and PC and connect via USB and you are connected.
I just did this and did a speed test over at speedtest.net and I got 145kbps for download and 34kps for upload. This is still decent speed through your BB and allows you to send email, talk on AIM. Obviously not good speed to download large files.
I still highly suggest downloading this application. Its one worth having!
