You can recover the password, the best way is to download a file manager to your phone. I use Best Fileman from http://www.smartphoneware.com/ It's for series 60, and series 40 (different download link). The trial version should be enough, it's only £5.60 anyway.
In the file manager you'll find under- C:\System\mmcstore -the file you're looking for, you have to rename the file- mmcstore.txt -then send it to another mobile or your PC via bluetooth (best way) open it on the other phone and your password will be revealed.
Rename the file- mmcstore.txt -to just- mmcstore -there might be another file named- mmcstore.txt -to view your password rename one or the other- mmcstore1.txt -one is for your phone PIN number the other your MMC card.
Clear enough?

Hi everyone

There's good news and bad news. The good news is that you might well have forgotten that the default password on the Samsung SGH-D500 phone is 00000000 (that's eight zeroes). The bad news is that if you've changed it to something else and that's what you've forgotten, you might well need to take the phone in to a service center to have them help you break it back open.Please put a good rating on my profile.

Kind regards
