Model number SCH-U450. There's a cable/wire that connects the keyboard to the screen, and its cut. I took it to Verizon (where i bought it) and asked them to repair it, but they said it was "unfix-able" and even if it was able to be fixed, it would be stupid because the repair would cost more than the phone. I really need this phone fixed. I'm willing to pay up to $250 for a repair. Does anyone know where i can take it? Best buy, maybe?
