My first torch was stolen over the weekend. I decided to buy a new Unlocked At&T Torch from a friend. After trying to change my device on my Provider's Site, I got a prompt saying the new device could not be detected. I gave my Provider a call, they said that my BB Data plan was active but if a BB is not bought from the Provider, BB Features such as BBM, Push e-mail, FB might not work.

And when i tried, these features really didn't work. I got prompts on the FB and Twitter Apps that my data plan did not support this. After searching the new for solutions, I ran a Network Diagnostics Tests. After which, my twitter and FB suddenly worked! However, my BBM and Push Email still don't work.

Any tips?

No need to double post. Your second thread has been deleted.

Do you have a BB data plan?

Did the friend cancel their BIS account before selling it to you? That will release the PIN so you can use it for RIM based services such as BBM and email. Sounds like that might be the problem.
