PS3 Downgrade for TI-84/89 Calculator

Brandon, maker of the PS3 jailbreak, hasn't been sitting still lately. PS3JB for the TI-84 calculator now offers a new feature most of the dongles out there support by now.

It's now possible to downgrade your PS3 with your very own calculator!

You can now downgrade the PS3 by emulating the Sony official jig stick.
You can enable this in the options menu:

Quotes from his twitter:

# Achievement Unlocked: Downgrade PS3 via 89Ti. Releases coming as soon as I can get them thrown together...
# Achievement Unlocked: Downgrade PS3 via 84+/SE. Hopefully the 89Ti will go quicker...
PS3JB - PS3 Jailbreak for TI-84 Plus/Silver Edition and PS3JB89 - PS3 Jailbreak for TI-89 Titanium
PS3 downgrade functionality added (v3.50 and below). Enjoy.
I added the files for both the 84 and the 89.

NOTE: This is not a payload for his old app, it's an updated app, so uninstall your old app and install this one!
