My friend gave me his iphone 4 and when I turned it on it came up with a picture of itunes and had the charger on the screen, I’ve tried to unlock it with my itunes but it won’t work how do I unlock it?

Tanya Templeman, I’d start by placing the phone into DFU. Plug your iPhone into your Mac or Windows PC and make sure iTunes is running. Hold down both the Sleep Button and the Home Button. Keep them both held down from about 10 seconds. Then release the Sleep button. Continue to hold down the Home button until a message appears in iTunes telling you an iPhone in recover mode has been detected.
