It will be coming out shortly. And Sony now has it that it is a requirment for In game music and Trophies.
EDIT:
"Hi, everyone. As many of you know, we released PS3 firmware update v2.40 last week, but had to take it offline temporarily because, for a limited number of users, the XMB wouldn’t display after the update was installed. We’ve been able to fix the problem, and I’m happy to report that firmware update v2.41 will be released shortly.
We want to extend our apologies to the PlayStation community for any inconvenience. Now we’ll be looking forward to seeing everyone online and racking up those trophies"
