of having the home button failed on me on two different iphones? the 3G and the 4. Exactly the same thing.. one day, all of a sudden, my iphone starts to miss some home button pushes.. sometimes I push it twice and only registers one click, or none, or whatever.. I remember the 3G failed after 9 months or so and my iphone 4 is now 7 months old. I don't abuse my phones and I really don't think I push the button too hard, or no harder than my previous ipod touch or my current iPad.. none of which has a failing home button.
