BTW. Why didn't you exchange your iPhone 4 if you home-button was faulty???
I had mine for 2 years (before I switched to iPhone 5), I didn't have any problems with it.

I had a nasty experience with a 2007 Macbook Pro 3 years ago. One morning the screen didn't come on. Fortunately I was in the US at that time. I went to the nearest Apple store and discussed with them. Turned out the issue with the screen was a known issue. They fixed it the same day. No charge because it was a known hardware-problem.
They are generally quite friendly when you talk with them.
