I’m lucky enough to use my personal iPhone to access Exchange email at one of my clients. They use Good Technologies as a mobile solution for all smartphones aside from BlackBerries. In any event, I’ve downloaded the latest version of the iPhone app (v184.108.40.2066), and was having some difficulties creating a multiline signature block. All attempts made my signature information show up on the same line.
After giving up for the weekend, I came back on Monday full of rest and coffee to tackle the issue again. (I mean what could be more important than my signature block?)
Then it dawned on me: use HTML tags. As soon as I put in the appropriate <br /> code in the right spot, everything worked.
