Magic iLife?

Well, out of the blue I was switched to iLife '09. I bought my MacBook in 2008, hence it came with iLife '08. But after the free upgrade to Mac OS 10.5.7, I magically have iLife '09, and it's not a trial version (I don't think). It has absolutely no "register iPhoto '09" or anything like that. No "you have 35 days left until your trial ends", none of the stuff that says this is a trial version. I have had it for over a month, but I think the trial might last for 60 days, so by June 25th we will have the exact answer. Sadly, my iWork '08 didn't update. I'll live. I hear one of my friends has a teacher that is extremely happy with iLife and iWork '06. Well, let's just say I'm a ittle more recent then that.
