I already have iPhone 4S but bought an iPhone 4 on craigslist to fix. Seller said it was a itunes problem..I got scammed. iPhone seems to work but screen is very dark blue and sometimes horizontal lines. So I am here looking for ideas. Thanks

Possible water damage maybe?

I also seem to have an issue with battery connect. It looks like all one piece that just screws to motherboard. Does that sound right? Thanks again and any input is appreciated. leslie
Yeah, the battery and the battery connector are one piece
Yea, the LCD screen and digitizer are one piece fused together (making it more expensive of coarse) and cannot be sprayed.
DO NOT buy any LCD/digitizer that are separated.....it is a scam, and you will never be able to use them.
