So my 32GB 3GS took a very unfortunate toilet swim yesterday. Stupid me had it in my back pocket & it fell in. I grabbed it out as fast as I could but the phone turned on while it was under water. (Yes water only!) Anyhow after drying it out fully it works but the back light won't come on and the sleep/wake button doesn't work. I have a genius bar appointment tomorrow, I understand I can get an out of warranty replacement for $199. I was wondering if anybody knows if they will take my current phone or will I keep it? I want to know if I need to wipe all my personal info & such off of the iPhone before I take it in. Thank You. And just FYI American Express has a buyer protection policy. Other credit cards may have this too. In my case within 90 days of purchase they will reimburse the original price charged to the AMEX card in case of accidental damage. This includes water damage! This is good to know if you damage your new iPhone (or any other spendy item).
