HTML5 Input Type Keyboards on iPhone & Android Devices
If you are building mobile web applications using things like PhoneGap, or jQuery Mobile you will want to take a look at some of the new values for the
type attribute in the
input tag that are offered by HTML5.
While these tags don't offer much benefit yet in desktop browsers, they do offer a huge benefit in mobile browsers. The different input types can be used to call up different default keyboard layouts on mobile devices such as the iPhone and Android based devices.

Here's a link to try these HTML5 form input types for yourself. Please feel free to post in the comments what keyboard your mobile device uses for them. That example page is using jQuery Mobile for layout.
