I have a jailbroken 3g 2.1 iPhone. I would like to update to 2.2 and jailbreak again. Do I simly hit 'Restore' in iTunes? When I click Restore the popup then asks if I want to 'Restore and Update'. Should I click that? I always heard you should restore before updating but I do not see any option to simply 'Restore' without the update. Just wanted to check this quick before I did anything. Thanks in advance.
