4. UPDATE YOUR SYSTEM MENU VERSION
Warning - If you don't install the patched IOS60 first you will brick!
This step is optional unless you are on 3.1, 3.3 or 3.4 in which case you must update, if you are on 3.2 or 4.0 you can update if you want and it is recommended that you do, if you are on 4.1 there is no need obviously! If you are on 3.1 you will have to update to 4.0 first, make sure you install the patched IOS60 first though still. Before you update to 4.1 make sure you have at least 250 blocks free or you will brick, install IOS60-patched first with Wad Manager using IOS249, then run Firmware Updater 4.1. If you are on 3.3 or 3.4 then you must update now - DO NOT install priiloader until you have updated as it will cause untold problems!.
