(1). There is no public API in iOS or ARM user mode instruction that reports the actual processor clock frequency.
(2). The Apple admission says nothing about clock frequency. Go back and read it.
So, yes, possibly fake.
so Apple continues to allow these "fake apps" that show issues with THEIR products in THEIR own app store?
If they were fake numbers, I'd bet the apps would be pulled and Apple would have made a statement stating that the Apps were reporting incorrectly to help quiet down this PR nightmare.
