If I replace my Ipod touch 4th gen screen with a local company other then Apple will the Apple warrenty be void or will the warrenty be void if I replace the screen myself?

Answer 1

Regardless of what Apple may or may not say about repair work done by a third party (a non-Apple company or you yourself), the Magnuson-Moss Act precludes them from voiding your warranty simply because you had work done by a third party or used non-OEM parts.  Typically people hear of thie Act as it is applied to cars. Car manufacturers cannot require you go to a dealership for repairs or that you use OEM parts. They cannot void your warranty for doing that. The Act applies to all consumer goods. Computer manufacturers cannot require you send your computer to them for memory upgrades or that you use memory supplied by them. Apple cannot require you to go to Apple for repair work or that you use Apple parts in that repair. 
With that said, though, if you have a problem in the future, Apple could make the claim that it was the result of damage from improper repair or substandard parts. Your only recourse would be the court system, not a quick or inexpensive endeavor.
