How can I disable the spell checker on text inputs on the iPhone

As noted by my buddy Jonathan Stark, you should be able to use attributes like autocorrect and autocomplete to achieve the effect you’re looking for:

<input type="text" placeholder="My Field" name="myfield"
    autocapitalize="none" autocorrect="off" autocomplete="off" />

Just tested in OS4 and it’s working.

UPDATE: As of iOS5 on and off values in autocapitalize have been deprecated. Use none to completely disable automatic capitalization.
