After watching the SDK roadmap video from Apple it seems a no-brainer that jailbreaking is no longer necessary since native apps will run on the iphone and most developers will want to switch over so that they get paid. With this new infrastructure in place, I can only begin to fathom the mass amount of apps that will spew from the app store. I, and i'm sure many other users with unlocked/jailbroken iPhones will want to tap into this resource. Is it reasonable to assume that when 2.0 comes out, we'll have to wait until someone figures out to unlock it. We'll update our phones to 2.0, and then unlock it, since jailbreaking will be redundant assuming that all of our current apps are reproduced via the appstore. Heck, my unlocked iPhone is already running on Roger's / AT&T, but who knows when the iPhone will come to Canada. Also, I'm completely uninterested in a slow data plan.
