Planning on turning on your PS3 for some The Last of Us action tonight? According to a thread on the PlayStation Support forums, if you're prompted to install the latest firmware update version 4.45 then you may want to hold of for now. A number of owners are reporting their systems locks up while booting, although the problem may only affect users with hard drives installed that are 500GBs or larger. According to the changelog, it was supposed to allow users to select whether or not they want an in-game notification when a trophy is earned. Check the thread for more details, if we hear more from Sony then we'll let you know when it's safe to press OK.
