IIRC correctly, EBJ definitely did not have the RC system, nor will the other returning 332 from JQ.
It definitely did not have seat back IFE when it was with QF originally.
I am certain that EBJ and EBK did have the Rockwell Collins system fitted, but not connected, certainly not down the back, not sure up front. It was delviered amongst the 4 international configured -200's, so it and -EBK are a bit of an odd ones out compared to the rest of the aircraft that ended up at Jetstar. Have a look at the pics in the trip report below, where the guy has taken a picture of an IFE box in Y, but no screen.
But getting back to what the plan is, any that have Rockwell Collins, or no seat back IFE fitted will have Panasonic system, fixed screens in J and I beleive BYO streaming down the back. This includes the 4 that are currently international configured.
Those with Panasonic fitted will have the system upgraded with new screens in J (obviously as new seats) plus old fixed seats down the back.
And for fullness the -300's new seats and system all round, including down the back, plus BYO streaming.
Those a/c returning from Jetstar that are yet to be reconfigured will have what ever system was in them. So for the early units it is main screen only, up front it is iPADs, but think they are pre-loaded rather than streaming.

PS tried BYO streaming on a 717 the other day and was reasonably impressed. Only thing I hated is if you locked the screen on the iPhone the streaming app would stop and had to be restarted again from scrach (i was listening to audio not watching a video).
