iRule how to use rewrite by same token ?

Yeah you can do with irule. Try below..

    when HTTP_REQUEST { 
      set id [URI::query [HTTP::uri] token]
      if { [HTTP::uri] starts_with "/iphone.aspx" } {
      HTTP::redirect "https://www.abc.com/mobile?token=$id"
        } 
    }

Do you want to rewrite or redirect?

For a rewrite:

when HTTP_REQUEST { 
  if { [HTTP::path] equals "/iphone.aspx" } {
  HTTP::path "/mobile"
    } 
}    

For a redirect

when HTTP_REQUEST { 
  if { [HTTP::path] equals "/iphone.aspx" } {
  HTTP::redirect [join [list "/mobile" [HTTP::query]] "?" ]
    } 
}        

Join command is there to add question mark only if query string is not empty
