Factory reset iPhone because I'm selling it. Some how it still has data on it. How do I completely get rid of this?

That's what I meant by "wiped". I still have this data on the phone. I've even gone as far to delete what I could from my cloud and I'm still having this issue.

Yes. Went through the whole set up as if it was a new phone being synced the first time and set up the phone for its first use. Ive done everything other boards say to do and yet this stored data stays every time. Im wondering if theres a way similar to Android where I can completely wipe the phone then put the OS back on....like a root.

I have turned off "find my iPhone" and reset through iTunes. Then itunes says "Welcome" I dont sync it. I then go through the actual phone set up with selecting language, wifi, location, etc. Here you have the option to skip Apple ID, passcode and wifi set up (which I skip all) and the phone takes you to the home screen. From there I double check to see if my usage is empty in which brings me here with this problem of data still being there even though there shouldnt be any. I dont even have this iPhone activated with my provider anymore so I cant send messages or make calls yet the data is there when the phone isnt active. Im just really confused as to why after wiping the phone I still have data on it.

When I purchased the phone used from Verizon there was no data in these spots...so your comment is odd to me.
