Im sure you have read it on other forums and even posted on some sites but yes a downgrader for 2.71 firmware PSPs is being worked on, will it come today, well its maybe and a maybe not, one thing i can say is that the hackers working on the downgrader (who i shall not name to spare them tons of people bugging them) have said a downgrader for 2.80 PSPs is not possible at this time but the good thing is that the 2.71 downgrader can also access Kernal Mode which has you know is great for any future releases wishing to push the most out of the power of the PSP.
As soon as the release happens and by that i mean that they have fully tested it and alls well we will have it posted on here.
With the incoming downgrader and eloader its an exciting time for PSP owners once again.
