how can i change font in iphone email editor?

That will work for the body of the message.

But what if you want to change the font in your signature on your iPad?

great thanks; this worked for me.

THat was really awesome, thanks from my heart

try this:

1. paste URL

2. shake device and select 'undo'

that should undo the automatic format change, I used it to edit my signature.

This worked for me. It's not really a fix but a nice workaround with an native iPhone app
