Well there is not much information yet pertaining to how this was done, but video proof has been provided as can be seen below courtesy of 0JOhnJAck0.
Now what is the significance of this you may ask. First off, I think its pretty obvious that this could not be done before. So this demonstrates just how far devs have gone with their knowledge of the PSP.
Of course one cannot help but to wonder if this will lead to any discoveries on Sony's other gaming device, the PS3.
Until more information about how exactly this was achieved on the PSP is released, we can only hope that it may assist in getting PS3 debug firmware running on the retail PS3.
