I don't know offhand. Did you use the switch device wizard to move to the 9800 from another blackberry, or did you start from scratch with he 9800?
You should try a hard reset first. With the power on, remove the battery for at least 30 seconds. Then try again.
If you used the switch device wizard and the battery pull didn't fix it, you could try deleting those apps, download and install them again, and then try to log in again. I don't know if that is the solution, but it won't hurt.
