Ok here's the deal. I really wanted an iphone bad. so i was on ebay and i came across this iphone that this man was selling. He said the only problem was that it had a dead strip on the bottom screen. When I recieved the package he was right. The bottom four bottons were not working(2g by the way). So I know its possible to increase sensitivity but here are my issue:
1. I cant figure out what firm ware i need to have to unlock with so i can get to the touch settings.
2. I can never open up the general plist file because i have windows
3. I can never figure out what firmware is on the phone because it is not unlocked
4. When I did unlock it i could never use cydia or installer because the bottom row was unresponsive
5. I cant take to apple because i dont have the data plan(bought it off ebay)
I dont know what else to do

some one please give me step by step instructions to fixing this problem PLEASE
