My iphone 5 will display itunes icon and wont do nothing else?

Plug in your iphone to your pc or mac open itunes and set it up

It means it needs to be connected to iTunes. Connect it to iTunes and it will start-up normally.

One thing that will always reboot the phone (not erasing data) is puting it into DFU Mode, look it up, it should help a bit!
