My iphone 4 is stuck on the logo of a charger to 'itunes'. I have connected it to my computer (same one as I always have) and it says that i need to restore my phone. So I did that. It reboots...then still says same thing in the beginning. My message on my laptop says that it is in recovery mode. so i shut off my phone. Waited an hour and restarted it. Nothing changes. Please help
