My iphone 3G has been jailbroken with 2.2.1 for a few weeks now. A few days ago iTunes has started prompting me to download an update for my iphone. I am obviously not downloading it, but I have not of heard of any mention of this on any blogs and what not. It's just annoying. Is anyone else experiencing this? And what is it for considering I have the latest iphone OS? *BTW I am running OS X.
