I'm not being smug, but I don't feel terribly sorry for iPhone owners if they hack their devices only to find their devices "incompatible" with future firmware updates. Whenever I've "hacked" a device (eg. a network router) it's usually because I've decided to install unofficial/after market firmware, at which point I no longer expect to be able to use official manufacturer firmware updates. Apple iPhone owners are in the same boat - only there is no alternative firmware, so what are they expecting? Cake and eat it? Apple Computer says "no"...
