ios App for Sleep/Wake Unlock?

Question

The normal way to unlock the iphone after waking up is to enter a 4 digit code. Does Apple offer some sort of iOS method for replacing this unlock screen with a custom programmed one?

I'd like to replace the 4 digit unlock mechanism with the android style "connect-the-points" unlock method. Such that when the user wakes the device up the user has to connect the points instead of entering a 4 digit code.

Does anyone know if this is possible on a technical level and if it is allowed by Apple?

Answer 1

Not possible with an un-jailbroken iOS SDK

Answer 2

2.4 Apps that include undocumented or hidden features inconsistent with the description of the app will be rejected
2.5 Apps that use non-public APIs will be rejected

As Andrew explained, it's not possible in the public SDK, there are no public APIs to replace this functionality.
