Some might think that I hate iPhone specific websites based on this opinion piece I wrote in which said I hate iPhone specific websites. Actually, it didn't say anything of the sort, but many read it that way. The point I was trying to make was that crafting websites which use browser detection to only allow the iPhone in is a step in the wrong direction (Eric Meyer, CSS guru, agrees with me so I really can't be that wrong.). That being said, since I have long been a mobile Internet user I am all for variants of websites that work well on smaller screens.
The Iconfactory's Craig Hockenberry has penned a great article (the first in a two part) all about making your website shine on the iPhone. He covers everything a budding iPhone web developer should know (which boils down to, ';Use standards!'), and points out some specific iPhone tags and tricks that you can use on your site.
