Too small to mention, but let me mention — Light_AleX’s PSN License Manager 0.22. We covered this awhile back and considering the changes aren’t anything major, I’ll simply repeat myself –

Use PSN License Manager to swap in and out licenses eliminating the need to deactivate/reactivate your hand-held; you know, when purchasing PSN goodies from different regions and such. PSN License Manager incorporates a “slot” system (up to 30) allowing multiple licenses to be saved in designated slots.

Don’t get the wrong idea now — PSN License Manager is not intended for distributing and/or using illegitimate licenses. It won’t happen. See the readme for usage instructions.
