Theoretically speaking . . .

If someone had 5.00 M33-4 firmware on a PSP, what restrictions would this impose?

Could the the console access/download from the PlayStation store and communicate with a PS3 without risk?

Is there a full list of features that such firmware would provide?

Anything else to be wary of?

 

I have 5.00 m33-4 and it's fine with store and everything else and linked with the ps3.

There is no negatives only positives and mine is custom firmware

 

Thanks
