I have about 10 months old iphone 4, and form last 2 to 3 months I started having minor issues with home button (ie: it dosnt work sometimes when I press or opens multitasking bar even with single press), it was less frequent initially and I ignored it for long time, but since last few weeks it got worst so I decided to visit apple store. I had an appointment and I went there on time, the guy asked me the problem I clearly told him what the exact problem was. He said he will take the phone inside for a while and do the scaning, Whithin just one minute he came back and said I need to close the applications running in the background form multitasking bar and there will be no problem. I thought he didnt understand what I was saying so I told him again and to show him the problem I pressed home button for about 10 times with enough interval so that it dosnt open multitasking bar and in those 10 tries it didnt work twice. Even after seeing this, he told me that I need to KILL the running applications and it will be sorted. I tried for a while and than gave up cause he was either not getting it or didnt wanted to. I was very calm and polite and I never said anything that can piss him off. But in the end I really felt it was such a waste of time and more than that I left the store with bitter feelings. Honestly I am very happy with my iphone, and I can just live with this issue given there is no other option. This was the first time I have visited apple store and I wish it was better expirience. Thanks for reading my ranting, but I had to spill it out somewhere.
