I've had the same Blackberry for nearly a year now, and for whatever reason when I last had to take the battery out and put it back in, my email didn't recognize the password, but not just for my email, any apps I had in as well. At first I thought it was because something happened to that password, but that wasn't the case. t ended up re-setting it and everything since everything but Twitter, Facebook, and my email ended up working. :(

Any suggestions would be greatly appreciated.

when you say reset the password, do you mean the blackberry password or the email and other email driven apps password? Were you locked out of the Blackberry? Pulling the battery wont reset the password. Please try to detail a bit.
