Official ios7 on iphone 5 typing extremely slow why?

I just finished updating my iphone 5 to ios 7 today 9/18/13. And the typing is extremely laggy and barely can make out words

Well, I'm guessing because apple didn't think it through properly and the while world is downloading it all at the same time, I'm guessing that's why
Mine is 90%bcomplete so excited

  • Will all my files be erased when I install the official iOS7? As y'all know, the official event is being held right now where the iPhone 5S, 5C and iOS7 are officially going to be released. However, I was wondering if all my apps and files will be deleted and act like a fresh OS once I install it.
  • Why isn't there an official PSN app? Xbox Live has an official iPhone app. The "My Xbox Live" app. Why hasn't Sony created a PS3/PSN app? Something that lets PS3 owners to send messages, add friends, etc.
  • Why is Sprint 3G Extremely Slow On Iphone 5? When I'm on 3G, no matter what internet connection does not work, going on the AppStore doesn't work, just to wait for a game to load it doesn't work! Like wtf? I'm truly lucky to have Wi-Fi, cause If I didn't I would lose it, but once I get off Wi-Fi, it's SLOW SERVICE! Sprint bills aren't cheap either, I have 2 iPhones on the same plan, what should I do please?
  • Why is my iphone charging extremely slowly? I have an iPhone 4S had it for about 3 years now and today it is charging extremely slow. It was on 90% and took almost an hour to get to 92%. This has happened before some months ago but I switched over the adapter and it was fine. This has not worked this time. Any suggestions as I can't afford a new phone right now
