IPSW stands rather simply for i OS Software, and IPSW files are basically just individual firmware downloads for specific i OS devices.
These files can be used to update i OS devices manually with the help of i Tunes.
A significant advantage to using firmware files can be found for users with limited access to broadband internet, where downloading a software update on a remote faster connection makes more sense.Typically you would then copy that IPSW file to a USB key or DVD to bring it home to manually update a device.Update: Apple's update to its newest operating system, i OS 10.3, is out and available for downloading.It's free, but before downloading, make sure your mobile files are safe and sound, just in case.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.Not all versions of i OS IPSW will work on all devices, so be sure to select the proper version for your hardware, and to use the latest which is supported.Software updates always come with the potential risk of data loss if an error occurs during the updating process.It's essential to back up your i Phone and/or i Pad every time you update the device's software. Follow this guide on backing up, restoring, and updating your phone and tablet.The i Phone 5 and later, i Pad (fourth generation and later), and i Pod Touch (sixth generation) can run i OS 10.
