On news of the PSJailbreak and it's 'Backup Manager.pkg', and the more recent news that Sony might be able to detect it, this idea came to mind.
The PKG file of the 'backup manager' is UP0001-LAUN12345_00-0000111122223333 vs the ID / PKG of Super Rub a Dub - UP9000-NPUA80063_00_VER02180407PACK1
So my theory is if we change the Backup Manager ID to something else, then sony won't detect it as easily. Sure there would be an huge amount of people installing Super Rub a Dub ID, but if 20 or so new/old ID were available, then it'll be a lot more hidden. Since the USB is allowing unsigned code, this should be still be Ok for the time being, until a new firmware comes out.
I'm yet to hex edit the PKG files and see if there are other references there, but if the USB device does allow unsigned code, then changing the PKG should be acceptable. Right? Any ideas, thanks for your time, looking forward to the device this week sometime.. already got mine on order.
