Hello "many more features which Apple adopted from the jailbreaking community that I know but tired of typing"
Oh and one more thing, Jailbreaking community should not be confused with iPhone user base.
How many of those can you prove were 'invented' by the Jailbreaking ragtag fugitive fleet? Just because they were first to the hobbyist/hacking users doesn't mean they were invented there, and they certainly haven't been perfected there.
But this is a pointless discussion. The Jailbreaking 'community' doesn't matter. It has no purpose other than planned obsolescence.
