DemonHades has released IrisManager for PS3 JFW DH 3.56 Custom Firmware. This is not the last version due to crashes on the payload screen.

Note: For those not on 3.56 already it is advised not to update to 3.56 CFW yet, as you will not be able to downgrade and IrisManager is barely working on it at the moment.
