how to change a template othe fly?

hello, everybody!
I have J!M on my site, it works good but there is one thing that...
while looking at an article page the page looks no good and I'd like to have a possibility to change articles templates on the fly.
if I'm from PC I use a normal Joomla article template and if I'm from a mobile device I'd like to use a mobile version of my article template ...
could you tell me how get to know that I came from a mobile device?
thanks for advance...

I got it:

$app = & JFactory::getApplication();
$template = $app->getTemplate();
//var_dump($template);
if($template == 'mobile_pda' ) $tpl='your_mobile_template';

ok, thanks...))

Hello,

I wasn't too worried about caching, I just needed a solution
But you're solution looks better if it achieves the same AND caches.

Not sure how your code decides to use ajaxChunk - how do I send it the parameter?

[!ajaxSwitch?
&ajaxChunk=`galleryHighslide`
&defaultChunk=`galleryStandardPage`
&cache=`1`
]]

Thanks & Regards,
Jacob

Thank you. You have answered the right. I also faced the same problem.

Try
$app =& JFactory::getApplication();
$app->setTemplate("template2");
