iPhone 3gs Home Button doesnt always work

[daniel101191]

My 3gs is only 3 months old, and the home button doesnt work every press, its also not very button like, it doesnt click or feel like a button being pressed. I rang apple and have book an appointment at my local apple store, has anyone experienced anything like this? do you think they will repair a button that only works when one side is being pressed in a certain way?

Kind Regards, Dan
