This release of JAF with new installer brings several improvements:

- you are no longer asked if you want new cable drivers, latest are installed,
- there is no need to launch PKEY Emulator, it runs automatically,
- you will no longer see "Box driver not installed" error

JAF allows you to upgrade, downgrade, cross-flash and repair dead phone using USB cable. No additional equipment needed (no box, no pkey) - though many functions require box to be present.
