Sorry I got nothing but bad news for you, first off apple wont cover accidental damaged so you may be charge up to 250.00 for apple to fix your iphone. Now you said that your iphone wont turn off, take the sim card out, if you have a back up phone put it in let the iphone Alone for 5 to 7 days and than try to turn it on, and see how it works, I've seen people that said the phone is working just fine, others the phone is just dead. Lest hope yours just comes back ok. Sorry good luck.
