Do I need an LCD screen for my cracked Iphone?

I dropped my Iphone 4 on the ground and the glass cracked. It's not preventing me from doing anything it's just very ugly and annoying to look at. Do I need to purchase the whole LCD screen kit or could I just buy a new front glass piece?

You need to replace your iPhone digitizer LCD touch screen glass. You can buy one with tools from ebay or amazon. But be careful if you are assembling it yourself because you can damage your iPhone LCD display screen very easily. You can find step by step tutorials on youtube for dissembling and assembling the screen.
