iPhone 4 stuck on apple logo screen?
Hello,
I have an 8GB iPhone 4 that I got about a year ago (some point in January 2012). It has always worked well however I did drop it last June but it only cracked the backing and I went to Apple and got the back replaced. Nothing was wrong with the software! Then today my twitter wasn't working so I deleted the app and downloaded it again, it froze halfway through the installation so I decided to turn my phone off and on again. I turned it off and then on but it got stuck on the apple logo restart screen for about half an hour. So I decided to reboot it (sleep button + home button) and it got stuck on the same logo screen for 20 minutes. Since then I've done countless reboots and plugged it in to my MacBook air; my phone didn't even connect. It just didn't do anything at all! Any ideas?
iPhone 4, iOS 6.1
