IPhone data won't turn off for certain apps?

Okay so about a month ago I reset my settings on my phone and since then, when I turn my data on it won't let me control which apps I use it for (I turn it off, leave the settings, go back and it's all turned on again) I have iOS 7. Does anyone know how to fix this?

How to change my Apple ID email?

I had an iPod and I used to use the Message app to text other people using my email as send&receive. Then when my dad and I first got our iPhones, we both used the same email(my email, because I got the phone first) address to set the phones up, and now you are probably wondering why using the same email… Well because the phone wouldn't let my dad to create his own apple account using his email, and it worked when we tried using mine and my password. So then somehow he could finally create his own apple ID using his own email later in the process and I went straight using my email(because I had an iPod and I just used the email on the iPod). Now I just noticed every time I send messages to my iPod, my dad would get the messages too. I'm very confused, and I tried to changed it in his account but I just couldn't figure it out. Can anyone help me please?

How to convert a.pdf into a.epub that fits well onto an iPhone?

Today, I downloaded calibre ebook organizer to change the MIT guide to lockpicking to an iBooks format. I succeeded in converting it into a.epub file but there's only a few characters on each page formatted like this:

---…
Recognizing

and

Exploiting

Personalit

y

T

raits

27

9.1

Which

---…

In the.pdf format it fit a lot of words but i had to zoom in and scroll weirdly within the page to read the whole thing. Any suggestions on how to format it so it is easy to be read?
(the conversion turned a ~50 page document into a 1705 page iBook)
