This question already has an answer here:
I was downloading iOS 7 to my iPhone 4 and the update was going for almost 1 day. I left it overnight and when I was about to use my phone it is stuck on the 'Connect to iTunes' screen (iTunes logo with a USB cord). My phone is still stuck on that and when I try to fix it with iTunes with my PC (Windows 7) the message always pops up saying that my phone needs to restore. Can you help me with this?
