Just curious if this is a common thing... My home button is screwed now, I have to push really hard to get it to register a click, double clicks often take a few attempts to achieve. My iPhone is out of warranty and looking at ifixit there's no way I can be bothered to do all that to change it, so I'll just upgrade to a 4S soon. But I was doing an upgrade for my mum when I was there the other day and her home button can be very sticky and temperamental... Then I mentioned it to my sister and she said her home button was awful (though not sure exactly why, she just said it was driving her mad)... Then just yesterday my gf's home button started playing up, although I think that one might be software related rather than hardware. Will try restoring the phone soon. All iPhone 4, all with dodgy home buttons... Is it really that common or is it just bad luck?
