So, I just got home about one hour ago and just took out my iPhone to check something, when I notice it was pretty warm to the touch. I take it out of the case to see the Apple logo on the front screen and vibrating once in a while, as if it was turning on. So I plug it into my computer. After about 2 minutes, nothing happened. I then look into iTunes and it was frozen! No matter what I try, nothing helps Any suggestions?
