Updating software on jailbroken iphone
The i OS user interface is based upon direct manipulation, using multi-touch gestures.Interface control elements consist of sliders, switches, and buttons.This is somewhat rare, but if an i OS update is interrupted it can happen, which usually requires a device be placed into DFU mode and restored manually with firmware.Typically a normal i Tunes based restore is sufficient, which is why that is fairly rare.Interaction with the OS includes gestures such as swipe, tap, pinch, and reverse pinch, all of which have specific definitions within the context of the i OS operating system and its multi-touch interface.Internal accelerometers are used by some applications to respond to shaking the device (one common result is the undo command) or rotating it in three dimensions (one common result is switching between portrait and landscape mode).
Jobs favored the former approach but pitted the Macintosh and i Pod teams, led by Scott Forstall and Tony Fadell, respectively, against each other in an internal competition, with Forstall winning by creating the i Phone OS.
You can use IPSW files on Mac or Windows, both require i Tunes to work properly.
To use the latest version of IPSW firmware files to update or restore an i OS device, you’ll want to be sure you have the latest version of i Tunes installed as well.
Going the IPSW route can take longer to update than using the newer OTA (over the air) method, the reason being that OTA uses smaller delta updates than the larger IPSW files, which are the full sized downloads and are often literally 10x the download size.
You can also click on “Restore” and select an IPSW instead but you will lose the existing files and settings on your i OS device.
