IPhone users: how can I get 4.6 GB?

I'm trying to get this update on my phone and it's not letting me so I deleted all of my apps for nothing but my mom told me that I need 4.6 gb and I re-downloaded my apps and some are taking too long to get back on my phone, someone and NO I do not have a Mac but someone please tell me how many apps I need to have so I can get this update going?!

Dude just link it up to iTunes. A popup should appear saying that there's an update. Say that you want to download and install. Then it will get to work. And just FYI, they do have iTunes for PC.

Here is a secret that everyone should know. If you do your update by connecting to computer then just click update when itunes asks you, you don't have to delete ANYTHING. Its also alot faster.

You can do this iOS 8 update with iTunes. But If you need more iPhone storage, just clean up your iPhone cache files, document &data and more.
