Note: I strongly suggest that you back up all the data on your phone before doing this. Remember, you’re doing this at your own risk (don’t say I didn’t warn you)!

Method 1

To fix this, I had to delete the BBM application, and reinstall it.

Originally, I wasn’t able to delete the BBM application, because it was a “core” application, so I installed the latest version from BlackBerry App World hoping it would overwrite it as an “add-on” application.

After installation, I rebooted the BlackBerry, and deleted the application from the “Applications” menu under “Options” (the wrench). Again, I rebooted the phone.

I found that my calendar was still defaulting to BBM Groups – despite BBM being uninstalled. If you don’t have this problem, then awesome, reinstall BBM at this point. If you do, then go to “Options” –> “Advanced Options” –> “Default Services” and choose your account, and press the back button, saving your preferences. At this point I found that my calendar now defaults back to the proper account – not to BBM groups. I then reinstalled BBM, and everything was fine, and my group memberships automatically came back.

If it really matters, this was done on a BlackBerry Bold 9000 running OS 5.

Method 2

Now, I haven’t actually tried this method, so I can’t verify that this works – but this is what RIM’s support group on Twitter (@BlackberryHelp) suggested I do.

“To fix this issue you will need to create a backup and perform a security wipe and do not restore BBM groups: http://bit.ly/di72gD ^CB”

Hope this has been helpful!

Before we begin: These instructions will only work on the most recent phones/OS’s. The latest Blackberry OS (v. 5.0.0.411)was leaked out on the internet, but any of the new phones (Bold 9700, etc. will work as well). More info available at http://crackberry.com/leaked-os-5-0-0-411-blackberry-bold-9000-and-blackberry-curve-8900

So, let’s begin:

Assuming you’ve installed the new O/S already, or you have one of their newer phones (I think most of the new ones with the trackpad instead of the trackball should be fine..haven’t tested any other than the Bold 9700 though.

Start by going to “Manage Connections” and select “Set Up Wi-Fi Network” then choose “Manually Add Network” (you can also scan, does prettymuch the same thing).

If manually adding, the network name would be CAMPUS-AIR

On the next screen, set the different values as follows:

• Security Type: PEAP
• Username: <your student number>
• Password: <your network password>
• CA Certificate: <choose any certificate, you’ll be ignoring it anyways>
• Inner link security EAP-MS-CHAP v2
• Token: <none>
• Disable Server Certificate Validation: CHECKED

Now you can save the connection, or if you don’t want to save, just click connect.

That should be it..
