"iOS 6 is a total dud. I think it's by far the worst major upgrade Apple has ever provided. It's more like a 5.1.2 than a 6.0," said BigBoss.
He notes the major differences moving to iOS6 from iOS 5:
1) Removes youtube
2) Removes google maps.
3) Adds apple maps. No street view, no transit directions. Remember, google has been doing maps a long time. No way apple is doing it as well in a few months.
4) Adds what? Facebook integration, ViP mail, do not disturb? iOS 5 users, you can get "do not disturb" functionality with "ringerx vip" in cydia.
This is definitely not worth an upgrade. And if you are jailbroken on iOS5 definitely do not upgrade to this. You will lose your jailbreak and that's definitely not worth it for this.
IOS 6 GM currently is a Tethered Jailbreak using the iPhone Dev Team's Redsn0w 0.9.13Dev4. Please remember this version of Redsn0w is intended for developers only. Check out that story here
