Yeah, that's until Battlestar Galactica takes one of those two spots. :D

Never had a problem with mine, but it's snappier after that, thanks Europa, good tip.

Any idea what the source is for this trick? I'd love to see their reasoning for why this supposedly works.

I tried it with mine (which needs a pretty deep press to work these days) and pressing lightly never took me back to the springboard. I slowly pressed harder and harder until Quickgoogle popped up (an Activator shortcut) and then springboard. I still need to do a pretty hard press to get it to work so I'm calling shenanigans. Lots of people have home button issues and I think someone made up some BS to get attention.

I agree. I think it's an actual hardware thing rather than software. The same method can be used to force quit apps, supposedly.

Jailbreak Activator shortcuts might conflict with it. It sounds like your phone is experiencing hardware problems with the home button and this will not fix that. While I don't think it matters if you press lightly or firmly for this calibration method, it does seem to work for many people. I wouldn't say that the fact that person who wrote this added in the word "lightly" automatically makes the entire method BS. When I searched again, I found the same method without the word "lightly."

iPhone software calibration is not BS. Every time you lock/unlock your iPhone, it automatically calibrates the screen. So I don't see why a method that also force quits an app couldn't possibly calibrate the home button. 4th generation devices seem to be particularity prone to home button software calibration problems - and this method sometimes provides a temporary fix.

As far as the source, an iPhone/iPad/iPod specialist did an AMA on Reddit a month or so ago and I found this in the replies. The quote that I copied wasn't one of his actual replies, but the method was mentioned several times and when a new person came in to ask about the home button he said, "Both things have been answered multiple times before. Search [this thread] for home button and calibrate." I don't know what his actual credentials are. I was just trying to help people here by suggesting a possible fix.

iFixit has tutorials for fixing the home button, which is not an easy fix. And of course, Apple will replace it for free if it's still under warranty. They'll likely replace it for free even if it's a few months out of warranty.

So, yeah, I don't have any supporting documentation from Apple or proof that it isn't BS, but a significant amount of people stated that it does help so I thought I'd post it here as a possible fix before resorting to hardware replacement.

What puzzles me is that pressing and releasing the home button merely opens and closes a circuit. It is either open or closed--on or off, no shades of gray. So I am not sure what there is to calibrate. I assume it is the length of time pressed. Regardless I tried the tip.

But alas my home button still does not register every time I press it. It would not be too bad if I didn't use double press to get to the switcher so often and it is double presses that are most affected. Maybe I will use activator to assign the switcher to something else and preserve my home button before it gets any worse.

One piece of evidence that would suggest this is not legit is that the Apple genius that replaced my original iPhone 4 definitely did not do this as a troubleshooting step. Obviously Apple geniuses don't necessarily know everything, but being that home button laziness is such a huge problem, you'd think this would be their first suggestion before a restore or replacing the phone outright.

Alright. Psylichon was right. I found confirmation that it's BS and does nothing more than force quit apps. I honestly didn't know this when I posted it yesterday. Sorry, guys.

I edited the original post so no one else will waste their time.
