Long story short Iphone dunked in salt water

OK, I'm stuck and don't know what to do....

I'm search and rescue and were pulled a guy from the atlantic today (deceased).

He was washing up on the beach in the wave action so I had to grab him and keep him from being pulled back out.

Problem is, the wave pulled me in to about mid calf. My Iphone 4 was in my leg pocket.

It got a dunk in salt water. It was in an otter box, but a couple drips came in the headphone port.

Yup, it's dead. It started heating up so I pulled the battery after taking hte back off.

After taking the phone apart a bit more, I could see where one of the connectors had burnt/corroded.

A though drying and cleanin g and I put it back together.

Now, nothing. Great, just great.

I try to hook it up to Itunes and it recornizes the phone!

Great I think, at least I can back up my apps, contacts, etc.

I click sync and it stops at "back up". I have a passcode on the phone and it wants it entered.

Well, no screen or touch screen because the phone is dead. Even tried tapping hte screen where teh numbers would be....no dice.

How can I backup my phone in it's current state without entering the passcode on the phone?!?

Please help, theres a lot of important stuff on my phone for my work.......

Also, once I replace the phone can I get my backed up files on to the new phone?

The original phone is a 32 gb Iphone 4 with the latest updates (5.1.1) but I'll probably have to go with the newer 4 S at a 300 dolalr purchase, a 279 dolalr buyout of my current contract and another 3 year contract....my service provider is nto willing to do anything to help me out either,

Boy that great customer servie from Bell/Aliant for a customer of 13 yearsisn't it?

Boooooo Bell/Aliant. I'm seriously considering a new provider now.....
