am I green?

I went to infomass today, the IO printed out the paper said both mine and hu*****and's I-485 got approval n 10/9, and card ordered. But in the web, neither of us's I-485 has updated since 5/15/2007 (we did FP on 5/11/2007). I asked the IO again, she said both of us got approval already. i wonder if I should trust her or the web? Does anyone have similair experience? thank you for your infmration.
