I think iOS is rock solid. IOS6 isn't a "big upgrade" compared to the jump from iOS5. Wondering why Apple doesn't create an easy short cut to have a drop down menu to access bluetooth/wifi/airplane mode. Of course, the pull down brings up the notifications. But apple can easily made a 2-3 finger pull down to access the short cut for bluetooth/wifi/airplane mode. This has pretty much been a simple request for the past 4 years with each IOS upgrade on the iPhone. Yes, Samsung has had this drop down on their Android phones for the past 2 years already.
