How do I clean install iOS 7?

[rekhyt]

I've got a 8GB iPhone 4 and I'm running low on space - only got 1.2GB left. iOS 7 needs 2.6GB free in order to download.

How do I do a clean install of iOS 7?

Thanks in advance.

Use iTunes and use the restore option.

Short answer... Grab the ipsw file, put the device into DFU mode, opt-click restore device, when prompted, point iTunes at the iOS 7 ipsw file, done.

Why DFU and why using an IPSW, why not just restore and that's it?

Maybe he forgot that iOS 7 was released to the public today. 😉

I believe restore won't do as clean as DFU mode

I believe restore won't do as clean as DFU mode

Why? What's the actual difference?

There's no difference.

The best selection is set up as new, do not restore to backup for most pure, trouble-free setup
