No, unless you use a mod-chip such as the E3 flasher or Infectus to downgrade your PS3 firmware by following a long procedure first. The E3 flasher doesn't require any soldering since you just clip it on, but if you want to dual boot between firmwares you will have to do some soldering. You can also use the Infectus without soldering anything using a solderless Xbox 360 Clip.
If you have any more questions don't hesitate asking.
P.S. In future please post any question regarding the PS3 in the "PS3 Help & Support" section.
