Or you can see if someone will swap ps3s with you. There's plenty of people out there wanting to hack there system but cant because there stuck with new ps3s (un-downgradeable) or don't want to open there ps3 to downgrade. 3.55 ps3s are scarce to come by. I say swap it out with a ofw 3.56+ ps3. It'll be a win win situation for both of you.
