I did not have ~3GB of space on my phone to update to ios 7, so I connected my phone and downloaded the update through itunes. As the update was being applied, itunes popped up with a message saying it could not connect to my phone because my passcode needs to be entered. Unfortunately, this was during the update process so I obviously could not access the passcode screen. Now, my phone is stuck with the apple logo and the update bar at 75% for quite some time. I've tried tried holding down the home button+power button to no avail. Any suggestions?
