EDIT: I unrooted and unflashed CWM and took the update and it was in fact the 3.1 update.
EDIT2: dr1337 has posted a ROM that is the official 3.1 OTA that you can flash if your rooted and have CWM if your tired of waiting on the offical OTA. I wish I didn't take the OTA as I lost my root and CWM but oh well. Here is the link for the 3.1 OTA ROM download:
ROM - Stock 3.1 4.010.07 - Update with CWM
