shoud I go for a infopass for my I485?

I filed I485 based on approved EB1a last July and got fingerprint taken last Sep. No update since then. I applied EAD and AP during this period and got both approved really fast. Is it very normal? Should I go for a infopass to check the staus? or the IO won't tell me anything as the processing date on USCIS website is still july 2007. Thanks for suggestions.
