If the Custom Firmware works like the PSP, you wont' need a JB device to start with. The PSP used a software exploit in the beginning (i do believe) and then it turned into needing Pandora's battery then another exploit (TIFF exploit?) and now its using another software exploit.
So, if they can get the PS3 anything like that, just depending on what firmware people are at (and 3.41 would be a good start since that's where the jailbreakers are gonna be). Wouldn't it be nice to have a TIFF exploit on the PS3? where all you need to do is use a USB thumbdrive to install a CFW on the PS3 which allowed you to load games from the XMB w/o even having to use Backup Manager? just have it listed in the list like the PSP does?
Sure, Backup Manager would still be used to dump games to hard drive, but wouldn't it be nice if they were listed in the XMB? Maybe have a 3.15 CFW that allows for OtherOS install. Call it something like 3.41-OtherOS or 3.15.41 or something (meaning OtherOS install, but current firmware... i guess that would be 3.15.42 right now?)
Of course have it where you can install PS1 games like you can the PSP. Also make it where PS3 games could be loaded w/o a disk in the console....of course, I am sure this is all stuff that is wanted by others....but hey, this is what we are going for right?
Am I the only one not crapping my pants in excitement? I say that because any CFW likely will need an exploit to install it in the first place... and there is no PSP port of the jailbreak yet. It's already been ported to a god damn toaster along with 80 hojillion esoteric phones no one has ever heard of, yet there has only been a peep so far about the possibility of a PSP version.
