Would it be possible to write an app where you can type in another email address in a from field? For instance, an app that can read the emails on your iPhone so you can forward/reply to them as another email address? I have several emails forward at the server level into my mobile me and it's be great to send from these as well. I've seen web services that let you have the sent address be anything you want, I was just wondering if there was a way for this to be integrated into the iPhone as an app? Thanks!
