Though I'm disappointed these features aren't backward-compatible for the regular iPhone 3G, I'm very impressed with what the iPhone 3GS can do to help users with disabilities better navigate the features that make the iPhone so fabulous. I would LOVE to have the zoom that they describe, as some apps don't support it on the 3G. Kudos to Apple for the thought put into making the iPhone accessible. I'm looking forward to what will be available in a year when I'm able to upgrade.
Thanks, Ben, for sending me the link!
