Most of the options would not be compatible with other styles as my Mobile style is coded with this in mind. Which aspects did you wish to apply to your other mobile style?
Edit: Sorry - I jest re-read your post. You could do this by manually editing 2 plugins
newreply_post_start and
newthread_post_start
Change the code from
Code:
if (($styleid==$vbulletin->options['mo37_mobile_style']) && ($vbulletin->options['mo37_post_text'] != '')){
$vbulletin->GPC['message'] = $vbulletin->GPC['message'] . "\n".$vbulletin->options['mo37_post_text']."\n";
}
to
Code:
if (($styleid==$vbulletin->options['mo37_mobile_style']) && ($vbulletin->options['mo37_post_text'] != '')){
$vbulletin->GPC['message'] = $vbulletin->GPC['message'] . "\n".$vbulletin->options['mo37_post_text']."\n";
}
if ($styleid==XX) {
$vbulletin->GPC['message'] = $vbulletin->GPC['message'] . "\n". "Posted via iPhone" ."\n";
}
Change the XX to be the style ID of your iPhone style and "Posted via iPhone" to what ever message you want, or
$vbulletin->options['mo37_post_text'] if you want the same message applied as from other mobile devices
