Added Viewport setting so zoom works correctly on iPhone, and iPod touch
The iPhone, and iPod touch display too many words per line when viewing single column pages. The double tap zoom does not work properly on some single column pages, and when you pinch zoom, the number of words per line is not reduced. The result is horizontal scrolling is necessary to read each line which gets frustrating after about two lines.
If you add meta name="viewport" content="width = 320" / to the HEAD section of your webpage, the iPhone, and iPod touch will render to a 320 pixel display, which allows the page to zoom to a readable text size, and be read without horizontal scrolling. I have added meta name="viewport" content="width = 320" / to each page on ConsultPDA.com so iPhone / iPod touch users do not have to horizontally scroll when reading this site.
Hopefully, Apple will add a setting to mobile Safari which will allow the user to display single column pages at a readable text size without horizontal scrolling. Many single column sites may never add the viewport meta tag, and viewing those pages on an iPhone, or iPod touch will require horizontal scrolling.
