hello everybody...i'm using firmware 2.2 and not jailbroken. when i download free apps from itunes store and sync it with my ipod touch. the itunes said "some of applications in your itunes library,including bla3 were not installed on XXX's ipod because you are not authorized for them on this computer". is that something wrong with my ipod or my itunes???? my itunes version is 8.0.2....what should i do with this authorized thing???
