XperiFirm is a small utility which downloads the latest firmware installation files for Xperia smartphones by Sony and by Sony Ericsson.
The layout of the program includes two panels; one on the left with a list of different phones and the right-hand side contains a list of firmware versions available for the selected phone.
Since XperiFirm connects directly to Sony services to download firmware, there isn't very much risk of bricking your phone if you use the official Sony Phone Flasher tool that's available.
All in all, XperiFirm is a useful tool which can be compared to other tools that have existed in the past and present like NaviFirm.
