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
