My Ipod Touch 4g is not connecting to iTunes. It is not recognizable for some reason when I synced it.. Help?

not sure how your ipod touch go into recovery mode but this is the only way to kick it out of it ok so simiple instructions hold the home and power on for 10 seconds and then without letting go of the power on triple tap the home on try this multiple times it took me 3 times when i just purposely put it in recovery mode like 2 minutes ago and i got it out and one thing you might wanna do if the update again isnt working uninstall itunes and re-install it but your probbbly wondering isnt all my songs and apps gonnna get deleted no as long as you bought the app and the songs from itunes it will auto back it up on its server or if you dont use itunes to buy songs you will have to back it up manually and if you still have questions or need help just click on my name and send my a email
