    1. Yes, u can upgrade to 3.71 M33 with the fatty
    2. Go to the baracode locate at the bottom of the psp. Check if it says 100X or 200X in the last few numbers. I heard that the slim internet lock tab is on the upper left rather than lower left.

    If your on 3.40 i suggest go back down to 1.50 then use mrgooey's guide

    because people who upgrade from OEA to M33 have bugs
