nope, sorry man, only sony has that, i think you can send it away (for a fee) and get it reflashed, but it comes back with the latest softwarte, but i guess 2.6 is better than nothing.
DAMN!! I had 1.50....... I went to the service and told them I want the firmware for version 2.00 that includes in the demo disc, so I can downgrade it by myself, and I hope it'll be okay!
