IOS21 is most commonly used by third-party games. It also contains some Broadway binary in content 1 in some versions, identical to the one in IOS15. Most debugging messages have been removed, though.
It probably had the connection fixes advertised for 2.2. Many games such as Wii Sports were also rereleased under this IOS with a newer strap screen, probably in response to TVs getting smashed.
This IOS was used by older versions of DataChk, a factory title.
