If you forgot your phone code, there is no way to get to your contact list....well, there is no risk free way to get to it. There is a utility (Samsung Code Reader) that you can use which will pull your code from the phone when it is attached by USB to a computer. But beware, as these applets are on sharing websites, so there is no tell if any of them are tainted with viruses.

Otherwise, if you are willing to forego your contact list, then you can hard reset your phone by following these steps:

A couple of things to mention:

1. This fix is NOT for unlocking the network (to use on other carriers), but rather this is for a 4-8 digit phone privacy lock that you may have forgotten what you set it to
2. If you run this fix, it will wipe out all data on the phone, effectively starting from scratch
3. You must remove the SIM card before initiating this or it will be wiped, also, leaving you with need to go buy a new one
4. You need to call Samsung to get the reset code: 800.987.4357 Tell them that you want to hard reset (wipe) your phone and you need the code. (They'll probably stay on the line with you and help you complete the task)

To hard reset the phone

1. Turn off the phone
2. Remove the back cover (battery compartment)
3. Remove the sim card
4. Turn on the phone
5. When it boots up and gets to the error message about the sim, enter the code provided by Samsung and press Return
6. Let the phone restore to original factory image and reboot
7. Turn phone off and install sim card
8. Replace back phone cover
9. Turn on the phone
10. You're ready to roll

SECURITY CODE:

If you are talking about the security lock code to enter into the phone then once it is lost nothing can be done except flashing the mobile . Because if anybody can give the security code created then who ever who steals your phone can get into it and get your valuable information.

So as safety precaution to avoid that they have designed it such that if you forget the security lock you have to reset the mobile memory by flashing the mobile at an authorized service center.So while flashing the mobile all the data in the mobile memory will be lost and you can again start using the mobile.
