On the status website, the application number gives you more information than the UCI (at least it does for us). And it gets updated at a glacial pace - for our application it only shows AOR, when we've already got sponsorship approval.
On a separate note, we experienced relatively quick turnaround time when we sent CIC an email about a misspelled name in our AOR. CIC wrote back within 24 hours confirming that it was just a typo in the AOR and that my son's name was spelled correctly in the application. Quite a relief, actually, because I can imagine a misspelled name in immigration papers could cause hours and hours of grief over many years!
Glad to see so many people getting their approvals!
