Both iPhone 4's I own on Verizon have issues with the home button being very mushy and sometimes being unresponsive. Made Genius Bar appointments and came in with both phones and showed the girl the issue. She had to click the buttons crazy hard to get them to work and deemed it ok... I kindly made a fuss about it and said I wanted a replacement for both devices since they were bought brand new without issue and this issue arose. This is what she said to me: "Yeah, this is a hardware issue and doing a replacement is just too much paperwork and work to restore everything. I would say just press the button harder." The store was about to close and they wouldn't budge on the issue...I am actually very disappointed with customer service here. This isn't the first time I've had issues with that Apple Store (Pheasant Lane Mall in Nashua, NH). A year ago when I bought my Macbook Pro there, one of the employees, dropped my Macbook Pro and tried to sneak it back in the bag...And when I said I wanted a new one, she gave me huge attitude. Lesson learned, I am never buying from that Apple Store EVER again and will talk with a manager tomorrow or something.
