Browser-Cache

Hi

in my .htaccess i have activated browser-chaching to make my Site faster and it works fine.... 

But if i launch my homepage eg with my iPhone, MobileJoomla works fine but if i switch to desktop-version this view is cached and if launch my homepage again the desktop-version will be loaded since i delete my cache......

what can i do?

i think i have to expand my htaccess with "if its an smartphone overwrite cache in the smartphone, else use cache..."
but i dont know how to do this...

could you help me?

thanks and sorry for my bad english
