v4.18 is I believe the way versions are reported in HBC (different to the decimal revision number). Having said that, there is no v4.18 of IOS36. Closest is v4.12 (revision 1042). [Converting the decimal revision to hex gives this: 1042 = 0x0412 = v4.12]
But yes IOS222 is a cIOS, so that is against the rules of these forums.
EDIT: revision 1042 is v4.18, because 0x12 = 18, as giantpune pointed out below.
