long story short: jailbroken 2.1, had categories (2 folders), installed 3.0 OS and apps are gone. i've checked new pages but there are only the search and main page. when i try to transfer purchases nothing transfers from itunes. when i try to download from itunes (on the iphone) it says the apps are already installed. are the apps still in the "categories" folders hidden and i can't search or access them on 3.0? do i have to jailbreak and download categories again for it to work??
