Just to give people a heads up - it's been released by brandon here: PS3JB89 - PS3 Jailbreak for TI-89 Titanium - Creating Payloads
He has (as usual) not included the possibility to play backups.
I must admit that I don't have the slightest idea on how to modify his source code, in order to make it able to load backups.
Can anyone who knows how to and has the time, take a look at this?
I will be you forever grateful
