I seriously doubt killing the jailbreak community will hurt anything....not that it will happen, but the JB "community" is more like a highly disorganized rabble of independent homebrew hacks.
Not that I've done anything special...but neither have they.
Yeah, those hacks. They haven't done anything special. Seriously? The jailbreak community is one of the more organized hacking communities around, and they've made using my iPhones much more productive. You may not like what they do, but it's naive of you to characterize the jailbreak community as disorganized and as having done nothing special. Because of them, people have been able to do things with their phones for years that iOS4 just now brings to the table.
