File System - The methods and data structures that an operating system uses to keep track of files on a disk or partition. The iPhone's file system uses two "disks". One is public and stores your media (songs, videos, photos, apps). The other is private and contains all the techy files that keep your iPhone's firmware running.
Firmware - The iPhone's built-in operating system. It controls both the "computer" portion of your iPhone and the baseband portion. There are periodic updates to the iPhone's firmware.
Fix My iPhone - Fix my iPhone was created when four entrepreneurs with vast telecoms experience set up Smart Phone Technologies Ltd. in the spring of 2010. With one aim - to provide the most professional and fastest iPhone repair service in the UK and Europe.
