added note about the details of the \text definition

this construction is simple enough that you can forget about redefining it for multiple sizes. instead, use the \text facility of amsmath:

\renewcommand{\atoi}{\text{\rotatebox[origin=c]{180}{$\iotaup$}}}

this can be used both in the "main line" and in super/subscripts of any level, and it should produce the desired result.

(the definition of \text is based on \mathchoice; take a look at amstext.sty -- it isn't very long.)
