Dropped iphone 4s and now part of the screen has a translucent white bar?

So last night I dropped my iphone maybe a foot and a half off of my bed (it has a case and I've done way worse) and it turned off. When I turned it back on there was a line through the bottom of the screen (no cracks) and a centimeter thick grayish-white bar through the length of the screen, with a black blob (I'm assuming where impact was) at the bottom. The guy at the Apple Store said they'd have to replace the whole phone which I can't afford. Is there ANYTHING I can do to fix this? I'm afraid it's getting worse, Please help!

The screen is indeed damaged, and as such, will need to be replaced. Unless the rest of the phone has been badly damaged, the screen will be the only thing that needs to be replaced. I know Radio Shack offers a screen replacement service, which is somewhere around $150 (depending on area) for the iPhone 4s. There are kits out there as well, if you are skilled enough, to fix the phone yourself for around $50 (give or take $35).

Don't trust the Apple store! They were gonna charge me $199 to get the screen replaced and I was not prepared to hand over that sort of money. I found this new site called iscreensfix.com, where you buy a new screen and replace it yourself. I was a little sceptical at the start, but I thought I might as well try because I could always get a refund. Anyway, I bought a membership, logged on and was guided through steps of replacing my screen, by following the guides and videos. I was also shown how and where to get a new screen. I was really satisfied (only cost me $17 and a new screen), and was able to fix the screen really quickly and easily. A five out of five from me, I'd recommend it to anyone looking to fix their screen.
