Why can't I update my iPhone 4 to iOS 7? - 1

I've been trying to update my iPhone 4 8GB to iOS7 all week, I realized I only have 1.0 GB of storage available when I need 2.8. I went and deleted all of my apps except for Instagram & Facebook and I still can't update to iOS7.Is anyone else having the same problem? How can I update iOS7?

Have you tried updating through iTunes if you use a computer (preferably a Mac) to sync your phone? You can perform a software update when the general tab is open.

According to my experience, I will Reformat the whole iphone (ensure that Backup all files into a drive) and then reinstall all files after updating my iphone. But the only to update your iphone is using a Mac.(Is good to use a Mac rather than windows co'z i will takes alot of Memory space) I think it will update if you reformat all first. (Make sure that your itunes is the latest version.)
Hope this helpful

Have you tried deleting some photos?

The deleting of photos totally worked for me!
