Problem with your phone arises from contact with water or extreme humidity.there are components called varistors that protects cpu from electrostatic discharge,and they are faulty.try to put a phone in a warm place,hopefully it will get dryed out and work again.other solution is to disasemble your phone and remove those faulty components

FIRST OF OF ALL YOU HAVE TO CALL YOUR SERVICE PROVIDER TO ACTIVATE GPRS ON YOUR SIM CARD (YOUR NAME SUGGEST THAT YOU ARE FROM INDIA SO IF YOU HAVE AIRTEL SIM THEN DIAL *567# OR HAVE TATA DOCOMO SIM THEN DIAL *141# TO ACTIVATE GPRS BY YOURSELF.) AFTER GPRS ACTIVATION AGAIN CALL CUSTOMER CARE AND ASK THEM TO SEND SETTING ON YOUR DEVICE(IN AIRTEL SEND "MO" TO 543210 FOR TATA DOCOMO SEND "INTERNET" TO 52270) AFTER RECEIVING SETTING SET THEM AS DEFAULT SETTING. NOW OPEN YOUR BROWSER AND ENJOY SURFING AND DOWNLOADING. THANK FOR USING FIXYA
If you have forgot your password, then flashing the ROM memory of your mobile in a mobile service center is the only way. Before that try with the default password of your phone. Refer your phone manual for it. Try 0000/00000/12345/1234/1111/11111 (any one of this may be default)
I suspect sand has got inside the phone and has got underneath the keypad contacts. You will need to take the phone apart and see if any sand comes out. So long as it didnt get wet the circuit should be working correctly.
Feel free to drop me an email. If you didnt want to fix it yourself i could take a look for you.
If it's the SGH-D900i phone that you have... Go to Menu... Settings.... Phone settings... Slide Settings... in there you have to change the "Down" from 'Continue operation' to 'stop operation'... save and slide the phone shut, that should once again lock the keypad.
