Ok so i unjailbroke my ipodtouch 1st gen 16gb on 3.o. Affter I unjailbroke it i sync it with itunes to get my apps and the other crap back when that was done i didnt even check if all my apps and other stuff were their i just upgrated it to 3.1.2 after that i unlocked the home sreen thing and every thing was there was there but my apps i had in catogories. But the apps i had in catogories are on my computer. My ipod says there is more apps then their are. My compuer says the same thing. And even the app store says i already have them so i cant reinstall them. What do i do?
