wet iphone 3gs.

[davidshell1982]

I have recently got my iphone 3gs wet and it didn't turn on for a couple of days, I dried it out using silica gel in a sealed bag, it eventually came on. a few hours later it went back off again and wont come back on at all. I have managed to save photo's, contacts using icloud but lost all the videos Ive taken of my 10 month old boy since he was born. is there anyway of retrieving them from my phone if I sent it out to apple if it wont turn back on? are they stored on a chip/built in memory card? any help would be greatfully appreciated. thanks.
