I just got finished replacing the lcd screen and digitizer on my Ipod 2g. everything went great but the digitizer still...

Vanessa I was going through the same thing and it sounds like your digitizer is broken. the digitizer senses where your finger touches on the screen. on the bright side the part is cheap and ther is alot of videos explaining how to repair it. So if you are willing to spend $10-$20 and put a little time in learining how to do it watching videos you WILL be able to repair it yourself
