iOS 7: FAQ, Changelog & Screenshots

Many forum members are curious as to what is new in the latest version of iOS 7 so I decided to start a thread with an FAQ, a changelog and screenshots!
(Yes, I saw the sticky thread here. But I felt like making one of my own. If any MODs feel differently, I'll happily abandon it.)

• What is "iOS 7"?
  iOS 7 is next generation operating system (OS) for the iPhone, iPad and iPod. iOS 7 was unveiled at WWDC 2013 in San Francisco, California on June 10th.
  
• So, how do I get it?
  Well, iOS 7 is in beta and as usual Apple has made iOS 7 beta only available to registered developers.
  
• But my friend has it and he's not really a developer!
  For whatever reason, some people have decided to pay the $99 registration fee and have become an official developer just to get access to the beta. Others have also paid for UDID slots to register their device on a developers account and then downloaded the beta from an unofficial source. If you are not intending to actually develop and test your own app on iOS 7 then it is not recommended you try to install it on your device. Any requests or offers for UDID slots is prohibited on these forums. See here for more info.
  
• Then when will it be available?
  This Fall. No more information was given by Apple.
  
• Is my device compatible with iOS 7?
  Currently, the only devices compatible iOS 7 Beta 1 are:
  - iPhone 5 (Model A1428)
  - iPhone 5 (Model A1429)
  - iPhone 4S
  - iPhone 4 (GSM Rev A)
  - iPhone 4 (GSM)
  - iPhone 4 (CDMA)
  - iPod touch (5th generation)
  
  Although iPad is not listed, it is expected to be available sometime soon.
  Compatibility with iOS 7 is subject to change.
