I want to get iOS 8 but I don't have enough memory?

I have absolutely no apps on my iphone, I deleted them all for iOS 8. Along with photos and videos, I sent them to another device to make memory room. And I have no texts either, I delete them. But it still says I need.8 gigabytes. I have no music or voice memos, no voice mails. My phone is basically empty but I do have contacts and stuff but I know that can't be taking up 2 gigabytes

Well whenn i got ios8 it said 0.94 mb so maybe use icloud for some storgae and then reinstal

I'm sorry to say this but you didn't have to delete anything. Do the update from itunes on your computer and you should be fine.
