Things like that i would suggest making an appointment at the Apple Store, usually when there is an issue with the phone it is the brand not the phone company ....
**or to fasten the process, go to apple.com , go to support, and live chat . The support group are very knowledgeable and will likely tell you exactly what is wrong with your phone.
Hey there lildl110,
Let's get that iPhone 4 to cool down. It sounds like the phone overheated and needed a bit of a rest. Is it still too hot to touch? If you've given it some time to cool down please try the restart method,http://vz.to/1ciOvXw.
