iPod Touch Screen Repair
there are many eBay sellers that offer replacement screens. If it is just a cracked digitizer (the glass) you can get a replacement for $12 to $15. Be sure to look for replacements that have the plastic frame/bezel included as well as the 'Home' button. If you can get one like that it's a simple snap-in to replace. If you don't have small tools many of the replacement kits include the tools as well. Good luck. I'm in the process of doing the same thing with my iPod.
