iPhone 4, Sticking Home Button

I have a four month old iPhone4,and recently the home button seems to stick, not allowing me to exit out of pages, apps etc. Or even to turn on at times. Has anyone else experienced this and if so, how did you get it sorted?

Go to Apple Store and they'll replace that. You're lucky it's still under warranty.

Make an appointment at the Apple Store (have to go through apple.com) if there isn't one within driving distance can be mailed in. Since it is an iPhone 4 it is still under warranty (they haven't been out a year yet) and that is a warranty issue they will either fix the button or replace the phone so back up before you take it in.

Happened to me. They replaced the iPhone4 at an Apple store.

Thanks all for the advice. I will book an appointment and get it sorted. Cheers
