Why can't i still update to ios7?

I have been to busy lately to sit down for hours and let my iphone update. So today i finally sat down, basically deleted 99% of the things on my iphone and it still won't let me update to ios7! It says you need at least 3.7mb(?) and i'm down to 3.3! Why can't i update?

All I had to do to update my iphone was plug it into iTunes on a computer and let it run its magic… Its way faster than trying to allow your phone to do it.

  • Why doesn't my iPhone 4 show ios7 update? I just heard that iOS 7 is available for iPhone 4/S, and when you go to settings-General- Software update it shows my iOS is up to date which is 6.1.3… And I just wanted to know why or is it really supported for the iphone4 I know that it lags cause iPhone 4 has a A4 chip not like the 4S which has a A5 chip…
