I recently updated the firmware on my Ipod Touch 3g. After this happened, the Wi-Fi and bluetooth were greyed out, an error I found was common among iPod owners. I tried everything I could find - putting it in the freezer, resetting network settings, resetting the whole ipod, etc. The only thing I can think of now that will work is downgrading the firmware on the Ipod. However, downgrading the firmware seems to require that you be in DFU mode. Apparently, Apple stopped offering the ability to get into DFU mode with the latest versions of OS X. Since I have a Mac with Snow Leopard, I can't get into DFU mode. Does anyone know of a way that I can downgrade my Ipod firmware with a Macbook with Snow Leopard? Alternatively, does anyone know any sure-fire fixes for this common problem? It's already been such a headache - I've spent so many hours in vain trying to fix this problem.
