iPhone Tab as seen on the Apple.com
Apple has made small changes to some of their international websites hinting at the launch of the iPhone in Brazil, Canada and Mexico. In the HTML source code for Apple's websites for Canada, Brazil, and Mexico, one reader found the following placeholder code:
This represents HTML code for an "iPhone" navigation tab wrapped in HTML comment tags so Web browsers will ignore it. When Apple removes the surrounding comment code, it will reveal an "iPhone" tab (see above) on these country's webpages. iPhone navigation tabs only appear on country websites with official iPhone support. At present, the iPhone has an official presence in the U.S., U.K., Germany, France, Ireland and Austria.
Apple's Worldwide Developer's Conference kicks off on Monday, June 9th, 2008 where Apple is expected to launch the next generation (3G capable) iPhone.
Update: The Canadian webpage apparently has had this code since August 2007, as first noted by Gene Rayburn. Mexico is also noted to have had it since August.
