template for iphone/mobile userd

Hi,

I am currently searching for a new template for my ebook store... www.theebooksale.com/zen-cart. I was recently accepted by mobipocket.com as a retailer, so very soon I will have several thousand ebook titles available in my store. Therefore, to mark the occasion, the store needs a serious face lift.
I have found a nice template that I can use as a starting point... and with some customization, it will be perfect. For an additional fee, the folks at algozone.com can create a iphone/mobile version of the same template. My questions are:
- how do I setup this mobile template?
- is it a fresh install (if so, how do I connect to the master database)? - or do I copy the modified template files into the existing installation and figure out how to detect an iphone/mobile user in order to display the mobile template?

Any help is appreciated.
Thank-you.

It would be most logical to ask *them* to answer those questions, since they're the ones building it, presumably including testing to be sure it actually works as desired.

Sure, I will ask them... but I'm sure other zen-cart users have mobile versions of their stores, and if so, how did they set them up? I already have a .mobi domain, so is this the place to install it? If so, is it possible to link it to the master database?

One way is to use different style sheets for handheld devices. See here: codinghorror.com/blog/archives/000782.html

Another way is to check if the device is a handheld device and redirect the browser to another website (such as m.yoursite.com) with a completely different layout.
