Hi you need to use {} to enclose your regex instead of "". Also for the iRule try this;-

if { [HTTP::header User-Agent] matches_regex {(Android|bb\d+|meego).+mobile|avantgo|bada\/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|Android|iP(hone|od|ad)|iris|kindle|lge |maemo|midp|mmp|mobile.+firefox|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)\/|plucker|pocket|psp|series(4|6)0|symbian|treo|up.(browser|link)|vodafone|wap|windows (ce|phone)|xda|xiino}} { 
     It's a mobile device
    if {[HTTP::uri] eq "/?fr=mb"} {
        HTTP::redirect "http://www.mydomain.com/" 
    } else {
        HTTP::redirect "http://m.mydomain.com/" 
    }
}
