Is Apple's security model for iOS with local passcode (simple or complex), 100% encryption, tracking, auto and remote wipe capability and the device is incapable of being used unless you log it in to it with the proper credentials so the activation server allows it to go past the lock screen whenever you restart it or even re-install the OS on the device.
I'm guessing if I say you should just get an iPhone that you'd complain about the "walled garden" and "overseer status" of Apple, which is of course ironic given that those exact features are what it will take to lock any phone from hackers and thieves. You need to make up your mind... customizable Android based phone or highly secure iPhone.
The way I see it is that such a secure setup could never happen with the Android system: No manufacturer wants to run stock Android as there would be little competitive differentiation. Since all Android installs are different you can't easily implement the activation server model or OS level encryption, plus who would do it? Carriers would want to raise prices to offer the service, manufacturers don't want to support phones for longer than it takes to sell them and Google doesn't seem to think security is a priority for the OS. Who's left?
