What does the digitizer replace?

Hello Jenkinsbyron, I am not the owner of an Ipod touch 5 Generation, but I just searched for some video arounds and the tutorial itself from iFixit, explaining how to replace the digitizer, as I could conclude the digitizer is a separate unit from your camera, the problem is that is so compact together that it may make you think some pieces could be together. I watched the video almost the whole length; I'm the fix man around my town and I do fix everything iPhones cracked screen mostly, and I build on my own my own electronic components, soldering components so small that would need to use magnifying glasses, and from my experience I would say this could be a medium hard process, for having a better notion I consider the iPhone digitizer replacement easy to medium.

The person on the video make it look easy but believe me or not if you are a starter with Fixing and you live in the USA, find someone next to you, a crazy geek who never goes out and only do that as amateur, and he probably would ask a cheap fee for the job plus around 60 for the digitizer. But this would definitely be cheaper than an Apple fix, or get fixed by services likes this one; http://www.iresq.com/ipod-repair.html
