Xperia PLAY :: Possible To Revert Back To 2.3.3?

I own an R800x, on 2.3.4, build number 4.0.2.E.0.57 (dunno if that's important), and subscribe to Verizon. Like most every Verizon subscriber who owns an Xperia play, I'm no longer able to sync with Google or pretty much anything else since the most recent update. I've tried talking to both Sony and Verizon customer support and they've both been equally useless, telling me to wait for an update which could be anywhere from a week to several months away, depending on who you talk to.Since I'd rather not wait for an update that may or may not be coming, I'd like to know if it's possible to revert back to 2.3.3, which worked just fine.
