Why won't my iPhone charge anymore?

My iPhone won't charge anymore. Its not the charger, I've tested many. I think either the iPhone recharge thing is melted, you can't see any damage in there though. And no, its nothing blocking the charger. I think its the battery that is dead. I've done lots of stupid things that i think helped damage the battery;

1. Brought it with me in the shower (self-explanatori)

2. Used it while recharging, wich made it very warm and maybe it melted, or just broke.

3. I've only dropped it once, a long time ago.

4. I charge it every night

Around 12pm tonight my charger got weird, it stopped charging and started again over and over rapidly. It continued like this so I stopped charging it. Today it died, because it stopped charging completely, then i blew air into the port, and the stop, start with the charger started again, but it didn't charge enough to start the phone… Any help?

Sims Freeplay Update - Real Estate Agency?

I just downloaded the new Sims Freeplay for iPhone 4S and I completed all the steps to making a real estate agency, except I don't know how to actually build it! The next step for me is to build the agency, and to select a lot near the beach to build it on, but there's nothing over top of the lot (like an add a house or add a sim) and when I click on a beachside lot, nothing happens?

IPhone/iTunes back up Info recovery?

I need help being able to access my old info.
This was 4 years ago, and I locked myself out of all my old info.
So I had to set up as new phone.

That info is still there, but I can't access it. I don't have the password
Is there anyway around it or am I screwed without it? :/
