iOS 8 update question

[justin_w_1982]

I have a 4S with 7.1.2. I wanna upgrade to 8, but it says I need 4.7GB of space. My iphone is an 8GB model, and before I delete almost everything to make room, I'm wondering if it will use the entire 4.7 permanently, or will I get a little back after the upgrade. I'm used to some stuff needing a little more space for the upgrade process and then releasing some of it back. Just wondering if that's the case here. All replies appreciated. Thanks, Justin

What happens if you upgrade through iTunes ? I've herd people said that it doesn't need so much space if you upgrade through iTunes

Hello, I'll use this topic to avoid create a new one, nothing's better than live on a clean forum, lol.
Question: I have iOS 7 on iPhone 4a, if I install ios8.1 on iTunes, how much free space I'll have after install? Thanks in advance
