If I Color swap my front screen on my iPhone 4 will it fix my broken screen too?

I just got an iPhone 4 and my friend dropped it and the front is cracked/shattered and someone told me if i color swap my iPhone front glass then it fixes the cracked screen does it work? Or will i have to get it repaired?

This will work, however you will need to replace the entire screen and not just the front screen. And I recommend using a professional repair program, that'll guide you through the process of replacing your screen to make sure no damage is done to your new iPhone 4. I used iscreensfix.com, and followed their repair guides and videos. Take a look at their site
