My son had clicked my ipod touch and disruppted the syc when I was trying to install an application. iTunes then prompted me by saying it failed to install the app. Duh. However, I removed the app from itunes then redownloaded it...but, it won't even try to install on my ipod touch anymore...i tried maybe 5xs now. I even closed both itunes and ipod touch...it won't even do it.... any help?
