Input type "email" instead of "text"

To prevent auto-capitalization in the email-form field on iOS-devices, I’d like to change its input type from “text” to “email”, as suggested here: http://stackoverflow.com/questions/5171764/how-do-you-turn-off-auto-capitalisation-in-html-form-fields-in-ios

Is there an easy way to do this? If not, are there other ways to prevent auto-capitalization and/or auto-correction on iOS devices (iPad/iPhone)?

Thanks a lot in advance!

PS. I’m aware that the capitalization of email addresses is irrelevant from a technical point of view, but many users find it disturbing.
