I'm new to the whole jailbreak scene - I only bought my first ever iPod Touch 4g last week. I installed the greenp0ison jailbreak but, I'm now upgrading to a larger one & selling this one I need to uninstall jailbreak and restore to 4.1.
I saved the SHSH blobs with tinyumbrella - this is because when I first bought it I upgraded to 4.2, but then wanting to jailbreak, I followed the guide on here to restore it to 4.1 & then jailbreak.
So my question is: can I just hit "Restore" in iTunes to uninstall the jailbreak, or perhaps will updating to the 4.2 through itunes work? Or are there more steps I need to take like putting it into DFU mode etc?
