I have a password on my Blackberry Bold that obviously works on the phone. However, when I connect to my PC to sync with Blackberry Desktop Manager, the computer asks for device password. I enter and it does not accept. It starts going through attempt 1 of 10, 2 of 10, etc.
I always have to disable the password on the phone, sync, and then enable the password again.
Also, is your password a number or what you think is a number?
For example, if your password is 4522 but you don't have to
press the ALT key, then in reality your password is SDEE.
