maxximuscool's SIM does not require a PIN (no PIN request dialog shown when booting Maemo in the video). AFAIK, pin entry is still not available (check http://qa-reports.meego.com) in Meego. So, you might want to try removing the PIN from your SIM (or, waiting until bug 13015 is fixed. (I have only tried Meego 1.1 image on my N900, and I don't think I had any GSM/3G connectivity, and my SIM requires a PIN. I will try later with a roaming SIM that doesn't require a PIN, and see if it is any better)
