So I made a few threads awhile ago about how whenever I turned my iPod off it would bring me to the screen with the USB and iTunes. Even after I restored it using DFU mode. Also how sometimes my iPod touch would say Dock Connector whenever I unplugged it from my USB connected to my computer even though nothing was connected. So I downgraded to 2.2.1 and none of those problems are there anymore. Does this mean I won't be able to upgrade to 3.0?
