I am an old Jailbreaker that has had a hard time coming back after iOS5. I really want to do this but my 1 main hang up is Siri. I am hesitant because when Apple releases iOS 5.1, I am thinking there will be some pretty big advances with Siri. DO you guys think this is a valid concern? Is Siri even updated in iOS versions or is it something they handle on the server side? Just need a push.TIA
