FORGOT YOUR SAMSUNG PINCODE? THEN TRY THIS

I was with my sister and a lady came up to crying that she forgot her pincode and she can no longer access her new Samsung GT-2121B phone, then we tried all we could to help her but to no avail and then we took to google and search out the solution, we were amazed to get solution to her problem right away and I think sharing such solution with you here is not a bad idea. If you ever forget your pincode on your Samsung  then remove the simcard and put on the phone and press this
code *2767*3855# you might not see the code but press carefully and wait till the phone reboot itself. you are on again, insert your simcard and begin a new life with your phone because your phone would be reset to its factory mode but the bad side is that you will lose all your saved files on the phone
