So, I've bought four apps from the app store (using my PC), and I've received four IPA files. I moved these into the iTunes library, and checked the "Sync Applications" box, then pressed sync. Everything runs through, it says installing apps, it even has them on the screen that organizes the apps, but when I check the iPod, the apps are not there. On any page. I have a Jailbroken iTouch, 3rd generation 8GB. Can anyone possibly give me any ideas on what I should do?
