The point of this thread is that the "simple passcode" does NOT need to press OK. With Android, there is no way to do this without rooting...even if you use 4 numbers.
But, my point above, which you apparently had no clue about is that Apple does allow the same flexibility as Android if you so desired. And if you don't, then there is the simple passcode option that allows for quick access.
Apple 3GS came out at about the same time as which Android? (June 2009) Name me an Android phone from that era that has JB or even ICS as official installment. You can't.
Now, while it is true that a FEW features of iOS6 is not present on 3GS due to lack of horsepower (CPU/GPU), MOST of the iOS6 features run smoothly on 3GS. Since I am not sure how familiar racer12306 is with iOS, here is a review of 3GS and iOS6:
Tempting fate: Installing iOS 6 on the iPhone 3GS | Ars Technica
"iOS 6 doesn't make the iPhone 3GS any slower or more difficult to use than it was before, which should be good news to anyone who keeps theirs around as a secondary or backup phone—indeed, it's pleasantly surprising how many of the refinements and improvements make their way down to Apple's oldest-supported piece of iOS hardware."
This is in stark contrast to rival smartphones introduced alongside it just over three years ago: the entire range of Windows Mobile 6.x devices, Palm's webOS Pre and Pixi, RIM's Blackberry 5.x lineup and all hardware running Google's Android 2.0 Eclair are not just unsupported today by those platforms' latest releases, but were in all cases not even supported through the first two years' contract life of those devices.
