Hey. Today I received back my iPhone 4 which I sent to repair last month because the home button started to fail. Apple has told me that they didn't felt it was broken, just natural use over time that makes the button less responsive... So now I keep having this problem. Clicking twice the button for multitasking almost never works unless I hit really hard and really fast. One click works normally. I have tried other iPhone 4 in different shops to see the responsiveness of the home button and I could see that they felt more firm and strong than mines. So now what? What can I do? I don't really want to change phone (neither 4S or Android). I hoped Apple service could have make it better but nothing, its still bad. Any suggestions?
