need help factory resetting an iPhone 4
It seems as though I am currently in the worse position possible for resetting my iPhone 4. The power button is broken so I can't Factory restore it that way,if I unlock it, it goes back to the apple logo by itself, and I can't reset it on my iTunes, because Find my iPhone is on. Am I out of options that don't cost money, or is there another way?
Thanks in Advance
iPhone 4, iOS 7.1.2
