In another thread you asked for the software to update the 8320 - which is obviously a very old BlackBerry.
The software and instructions can be found here -> Latest OS: 8320 126.96.36.1993/188.8.131.52 (Multilanguage)
I am fairly sure (ancient memories) that the 8320 has password keeper. When running the installation program, make sure it is checked off.
Follow the instructions in the thread to the letter and good luck...
