Long story short I've got a 2g ipod touch that has water damage. Restored it with iTunes to v 2.2.1 and it would reboot constantly. Put v3.0 on it and now it'll boot find but the touch screen doesn't work anymore making the device basically uselses. New screens and/or digitizers are available on eBay all day long, my question is since the screen looks great (as in no dead pixels and what not) the touch part just doesn't work, do I need to replace the screen or the digitizer? Thanks in advance.
