To Manually Reset the Passcode: 1) Install any desktop software for browsing the iphone filesystem (iPhoneBrowser/iFunBox/SSH/DiskAid trial version).
2) Navigate to the directory /var/mobile/Library/Preferences/ and delete "com.apple.springboard.plist"
3) Then you can navigate to the directory /var/Keychains/ and delete "keychain-2.db"
4) After deleting the last file, reboot the iphone.
To give you an idea on how this worked, the com.apple.springboard.plist file contains the setting of your passcode turned-on. Deleting this resets the toggles back to default (after the final reboot) and takes care of that part of the problem. But since a passcode was already defined, the "keychain-2.db" file contains that information and deleting it clears everything up after the final reboot. Note that all other stored passwords you have on your iphone are also cleared along with it though.
