How do you remove all the dirt and corrosion?
Get 99% Isopropyl alcohol, take the phone apart and let it sit in it for a day or 2 to clean off any gook and let it dry throughly,
I cannot think of it, but there are 2 types of water(ironic, I know) that will do this, I don't remember what types
NEVER put the battery in no matter what, you may short it and it may work!
In regards to the screwdriver, it will need a Pentelobe screwdriver, I do not think radio shack sells that, but they sell the phillips you need, water sensor wise, there is one in the headphone jack , one in the dock connector, some in the phone
Here is the water damage guide
and the pentelobe screwdriver
Also, IPA stands for isopropyl alcohol
When you asked about accessory and why I am afraid if apple, I thought I would take a few minutes to explain now when I should be in bed, so that version of accessory means I helped you do something illegal and I knew that, so the court can potentally get a warrant and track our IP addresses, come to our houses and take our computers, heck, we might even be in jail
