my iPhone 4s is frozen. the touch screen doesn't work except the help tool I have because my power off button is jammed. my messages all pop up still its just the touch effect isn't responsive. I haven't payed my bill yet so could that contribute to this?
Have you tried plugging it into a charger? I know that sounds pretty random but you could try ( I used to have an ipod and that taught me to try everything to unfreeze it lol). But as Dennis said, visiting an apple store is recommended.
