If you're making a website and you want it to look ok on an iphone or other "small screen" devices, do you have to have a customised version for those devices so that it is easy to use? If so, how do you detect what the device type is and what do you have to do to make your website usable on a small screen device? (I've never used an iphone etc. so I don't know how well it works for surfing the internet.)
