Help!

My iPhone 4 is screwed up. I updated it with the most recent update, and when I did that the home button got loopy. It would act as though it was being pressed constantly, even though it was not physically pressed down. Therefore it would constantly go to the main home page, voice command, and the search page. It fixed itself after I turned it off for about 20 minutes. However, just a few hours ago it started again, so I decided to restore it. I restored it, and it was being reloaded from my most recent backup and after it completed backing up, it said the normal, please keep iPhone connected as it restarts. When it came on again, it was back in recovery mode, and needed to be restored again. I did this 3 or 4 times. I even updated my iTunes and tried 2 more times, but it will not come out of recovery mode, no matter how many times I restore it...
Please help! Thanks!

 

Hey guys, sorry about the thread title as I am new to this site. Can I update the title?
Also I just tried the DFU mode or whatever, and that did the same thing? Anyone else have any ideas, or should I just take it into Apple?
Thanks again guys

 

Was that really necessary?

Anyway, I brought it to the Apple Store and they replaced it. They couldn't figure it out either. It was in an infinite loop. Thanks to all that helped!
