Yeah, we can make iRule to match phone browser's 

User-Agent
header & display message or redirect to webpage.

Example

    when HTTP_REQUEST {
    switch -glob [string tolower [HTTP::header User-Agent]] {
        "*iphone*" -
        "*android*" -
        "*windows phone*" -
        "*windows ce*" -
        "*bada*" -
        "*bb10*" -
        "*blackberry*" -
        "*symbinos*" -
        "*symbain os*" -
        "*symbian*" -
        "*java*" -
        "*winowsphone*" -
        "*windowsce*" {
                HTTP::redirect "https://[HTTP::host]mobile.aspx"
               }
            default { 
    HTTP::redirect "https://[HTTP::host][HTTP::uri]" }
    }
}

Try switch condition in iRule. Example. 

switch -glob [string tolower [HTTP::uri]]

And add HTML syntax.

    HTTP::respond 200 content { "Mobile PageSorry! This task is not available on the mobile app. Log onto your desktop to complete this task..."}
