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.
