My iphone 4 screen is ghosting?

I just purchased a iphone 4 off ebay. I noticed that after spending time web browsing my nav board ( the bar on top with the clock, carrier, battery) i found that when i leave to another app or something there's a pink ghost of the bar where it was… I have never owned a iphone so i do not know if this is normal… But i had a ipod touch 3g and it never did that… Will it always do that?

Should i get my money back?
Should i deal with it?
Is it normal?
What causes ghosting?
Is there a way to fix it?

I owe someone money, but they stopped contacting me. What should I do?

I bought an old, cracked iPhone from my friend for $35. I was going to pay her after I got paid. I now have the money, but we have since had a very messy falling out. I'm not even sure if we will speak again. I told her once "let me know when you can come get this money." And she said "okay." About a week later I texted her asking "are you ever going to come get your money?" And she didn't reply. Should I just spend the money and pay her if she asks again? Or should I just completely forget about it?

I know this might seem like a big deal for $35, but I'm trying to do the right thing.

Any iPhone App that recognize Classical Music?

Does anyone know any app that would enable us to recognize classical music?

(I also have my BlackBerry so either would be fine.)

I want the iPhone so bad but I also don't want to get it and have my bill be sky high even though its "unlimited" how much is the bill and will it stay the same since its unlimited?
