I've got an iPhone from last year's i-Friday and have never had a problem until now. A few days ago, some of my buttons are sticking or stuck ( dead ) and do not work.

This holds true on the home screen, the "send" button on texting and a few other vital places.

I have followed all of Apple's troubleshooting suggestions like powering off, reset and refresh with a update but they remain dead ( stuck ).

Has anyone else experienced this and or what would you all suggest since my warranty exoired three weeks ago?
