How replace flash for images

I need to now how replace flash banners for images just in iphone templates with mobile joomla. Can I have a diferent template in iphone or ipad and android, other than my tempate in Internet?


Thank you!!!

MJ uses special mobile templates for mobile websites, so if you banner is a modules, you can use an image instead on mobiles.

Thank you for your answer, but how can I do that?
There are tutorials for that ?
