So I got my 8GB iPhone 4 in February 2013. It still has iOS 5 because that's how it came and I never updated it. I wanted to update it to iOS 7, but my phone says I need 3.7 GB to update it. I deleted a bunch of stuff from my phone, restarted it, and it still says it needs 3.7 GB. Someone help? I don't want to do a factory reset thing either. Would it update if I connect it to a computer and do it through iTunes? Someone help please! Thanks in advance x
