Recalibrating your iPhone/iPad home button →

Dr. Drang, at the end of this post about killing apps in the multitasking switcher:
There’s another bit of iOS voodoo floating around that I’d like to see Fraser tackle: recalibrating your home button. My gut feeling is that this, too, is a waste of time.
I tried the “recalibration” procedure a few times on my iPhone 4 and iPad 2, both of which slowly developed unreliable home buttons.1
It seemed to help for a few minutes the first time, but later attempts showed no improvement, so the first time was probably just coincidental. I think it’s safe to say that recalibrating iPhone or iPad home buttons is a myth.
Anyone have any solid knowledge to the contrary? (If an Apple “Genius” told you, that’s not good enough.)
Update: I’ve received numerous reports, some from current and former Apple employees, that “recalibration” is indeed bullshit. Grant Paul even reverse-engineered the OS routine being invoked by the extreme long-press and confirmed that it only force-quits the current app. Nothing more.

The solution for the iPad 2 was to bring it to an Apple store, where they replaced the entire iPad under warranty as a result. The iPhone 4, sadly, was out of warranty by the time its home button started getting noticeably unreliable, but it was never as bad as the iPad 2’s. ↩︎
