My advice would be to try out Evilnat D-PEX for yourself, and if you decide you want to go back to Rebug then you can.
 
This interests me as i am still on rebug, 4.82 D rex
I am more than happy with it,
only reason really to update is to take games online.

Is it really as simple as updating to Evilnat,
and if wanting to go back, updating to Rebug 4.84 ?

Only reason i havent been doing it, is wondering if games and emulators etc will continue working straight up
and options set up needing re doing
 
If you have set QA flag, you can freely going up and down to any CFW (min ver is factory fw ver set; going lower means perm brick beyond repair, so console will not allow you that even with QA set).

How can I dualboot different versions of CFW & OFW? I'd like to boot one version off the HDD & another off USB stick possibly.
