My iPhone's screen cracked, Screen white afterwards. Help me fix it!

I hate to be the bearer of bad news.. but it is called the "screen of death". Your LCD display is broken and needs replacement.. your Digitizer is what responds to touch which is working, but it all gets replaced as one piece. There are plenty on people that fix these problems fairly cheep (approx. $20-40). You can purchase a new screen on eBay or Amazon ,and for some repairmen will reduce the cost of the fix and labor is all you will be paying for. If you are skilled, you can do it yourself like I do, but you have to be VERY careful and know exactly what you are doing or you can just make it worse... Well I hope this helps! If you have any questions, ask away! :)
