I need to remember my old password so I can replace it and lock my phone

If the phone has a previous password already, you can't really change unless you reset the phone, that is the only way to change it.

reseting the phone will delete all information on the phone.
but information on the sim and on the memory card will be save.

call 1 888 9874357 for further assistance on reseting the phone without going to the menus.. :)
