A View of Different Pages
If you are a Windows 7 phone owner, you may have noticed that your phone has different pages that you can engage with. This is intentional, of course, and allows for users of this phone to get access to exactly the information that they want at any time.
Developers look at this as somewhat of a challenge. They need to figure out how they can keep certain bits of information from page to page while transferring other bits, and it is all about what they think their users will need to see from page to page.
