What the heck happened to my iPhone 5?

Okay so I wanted a new ringtone and I downloaded it on my computer and it gave me instructions on how to transfer it to my iPhone 5. But the trouble is I'm completely new to this stuff and so I connected the USB thing to the phone so I could import it there and then it said I needed a new update first so when it finished loading it said it couldn't be completed. Then next thing you know my iPhone screen was stuck on the iTunes screen so I used a new USB connection thing and connected it to my mac and then I wanted to download the new ringtone but then my iPhone restarted itself. It asked Hello. Then it started asking questions like it was totally new again like "Country?" WHAT THE HECK HAPPENED?!

Does the ios7 for iPhone facebook app save multiple login emails?

Or is there an app that does? I have two fb accounts, one for work and one for my personal/family/friend life, and I hate having to type in the email address each time I switch accounts and login.

Currently I have the older version of the fb app on iOS 4.3.3 the only reason I would consider upgrading the iOS is if the new upgraded fb app eliminated this extra step. I don't really like the new look of iOS 7, especially the texting skin with the colored bubbles and white text, all on a blaring white background.
