Your desktop website might look ok in Safari on your iPhone, but is that what mobile users want or expect?
We can set up your website to detect the visitor's browser and show them the appropriate version of your website. If someone visits via iPhone or another mobile browser, they can get the mobile "theme" instead, which can be totally customized. You can even show a mid-sized version to an iPad or tablet device

In the above example, you see the Boegerweb desktop theme and, inset, what the mobile theme looks like on an iphone. You can see the mobile them on your desktop if you visit m.boegerweb.com
You could also set up your website to be mobile-centric in the first place if you want, and take advantage of "native" functions on iOS and Android such as maps, pictures, and sharing.
Take it a step further and we can develop an App for the iTunes or Android stores that pulls in and interacts with data from your website. There are endless possibilities and Superclean is working a lot in this area. Please let us know what features would interest you in Mobile Web Design.
