Password My phone is currently locked and I know for a fact what my password is, but it keeps saying it is invalid. You only get 10 attempts and then all the info will be deleted. I'm on my last attempt. I called my carrier and they had no helpful advice.

Woah! DON'T put it in again. it will fry your sim card. call customer care (1-800-331-0500) and they'll help you unlock it. if you do fry it, then you would need to get a new sim card.

Cannot unlock my kepad as forgotton what i chose as keypad lock password

Your only option is to keep entering passwords and once you have 10 incorrect attempts, the device will be wiped back to Factory Settings (data gone for security of lost devices). You can then reintialize the device with a new password of your choice.

Locked blackberry

just use up all the attempts to unlock the password and the phone will atomatically wipe itself and then you will be able to set up your own password.
