The power button on my iPhone hasn't worked for a while, and I need to get it fixed. But tonight, I was listening to music on my phone, I get on to make a call, and suddenly my touch screen doesn't work. The phone still registers (e.g., if I plug it into my computer, it will download things.). Also, while at first the touch screen wouldn't even fade to black, it's doing that since I plugged it into my computer. Still...no responsiveness from the touch screen. So what can I do, if manual reset is currently not an option? Do I have to go into iTunes and restore to factory settings? Is that even likely to work? Thanks.
