New years eve camping i had a memory blank from about midnight to about 4am. The next morning i was told i went for a midnight swim with a bunch of mates. i couldn't find my iPhone and totally had no recollection of this swim. My friend happened to have his laptop with 3G card thing and i managed to log into my .me account and track my phone down the beach. long story short i found it full of sand and a little damp still in my pocket neatly folded in a pile down the beach. The phone to my surprise was still working fine, but the audio from the iPod wasn't, nor were games. now i tested the ring tones they were working fine. I got into town and we had to pump the tires up so i used the air gun at the servo to blow out most of the sand in the docking part of the phone. This worked and the sound came back on from the games and the iPod. now since being home the wi-fi has decided to show up grayed out and saying no wi-fi available also my BOSE dock which i normally plug into to listen to podcast, music etc, that too is not working no more.. on the phone it reading: this device is not made for the iphone blah blah blah.. any tips please would be greatly appreciated. It is still under warranty should i just send it back to apple>?
