AN INTRO ABOUT WINDOWS PHONE 8.0:

• Windows Phone 8 is the second generation of the Windows Phone mobile operating system from Microsoft. It was released on October 29th, 2012, and like its predecessor, it features the interface known as Metro (or Modern UI).
• Windows Phone 8 replaces its CE-based architecture used on Windows Phone 7 devices with the Windows NT kernel found on many Windows 8 components. Current Windows Phone 7.x devices cannot run or update to Windows Phone 8 and new applications compiled specifically for Windows Phone 8 are not made available for Windows Phone 7.x devices.[2]
• Windows Phone 8 is the first mobile OS from Microsoft to use the Windows NT kernel, which is the same kernel that runs Windows 8. The operating system adds improved file system, drivers, network stack, security components, media and graphics support. Using the NT kernel, Windows Phone can now support multi-core CPUs of up to 64 cores, as well as 1280x720 and 1280x768 resolutions, in addition to the base 800x480 resolution already available on Windows Phone 7. Furthermore, Windows Phone 8 also adds support for MicroSD cards, which are commonly used to add extra storage to phones.
• Due to the switch to the NT kernel, Windows Phone 8 also supports native 128-bit Bitlocker encryption and Secure Boot. Windows Phone 8 also supports NTFS file system due to this switch.[10]
