hello, I was given a free water damage 3gs today and the owner said it was not turned on in months after drop it was very slight he put it in a bag of rice and left it there for a month. So I check it out the water indicators are orange so water got in. But I noticed when I turn it on for the first time since this happen apple logo and than usb to itunes logo. So will the phone work with a update? Never been unlocked currently has 3.1.3 bb 05.12.01-6.4_M3S2 so any suggestions would be great also should I fully restore update it with current fw from itunes?
