Ok i just got my new ipod touch 8gb 2nd gen like 3 days ago and i download some apps. it worked fine and i synced it with my computer. thne 1 day later i download some more apps like free text. the apps worked fine until i synced it with my comp. after syncing i tried some of the old apps it did work. the apps would appear for a couple of secs and turn off. the new apps did the same. i re-downloaded the apps and still didnt work. i backed up up and it didnt work. any ideas?
