I think that if the button is faulty it falls under warranty and you should be able to exchange it for a working iPhone 4 for no extra charge. If you have put alcohol in it, you have probably blown whatever warranty you had left.

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.

I don't live in US, and here the service provider told me I would have pay.
