I fill out webforms on my iphone fairly often. I use autocomplete to speed this process along, and it works pretty well for the most part. However, for some reason, it always insists on using an @facebook.com email address in the email field.
I do not use Facebook for email. I never have, never will, and never want to. I do use Facebook for lots of other things, and thus, would prefer not to turn off iOS's Facebook integration, which seems to be the only workaround that googling has offered me.
How can I force auto-complete to use my preferred email address, rather than the one associated with my Facebook account?
