No
you have to buy a digitizer of amazon or ebay
if your ipod touch has lost it touch, that probably means the screen is broken. if it has cracks, there is another sign. my friends lost her touch and had to order a new screen from apple, or go to the store were you bought it.
There is not a way to adjust the sensitivity on the screen of your IPod Touch. If you think it may be broken you can send it back to Apple to have them fix it though.
REBOOT, but DON'T just Respring
Restore the iPod to the last restore point. You can do this in iTunes.
contact apple and they will fix it for you for $90 to $100 or if you have warrenty then they will repair it.
You need to remove it then reinstall it
All you have to do is hold down the top bottom with the home button. This worked for me when my ipod touch did that, hopefully it helps you!
i think nowhere... $150 is the cheapest i have seen someone pay to get the screen fix
