All emails sent from my iPhone get a signature attached that says ‘sent from my 3g iPhone’. This is just a slightly modified default signature which I’ve never changed. I was asked about this recently and thought I’d share it here.
The signature serves a few purposes. Recipients need to know the email came from the iPhone because:
Emails are shorter and more focused due to the lack of proper keyboard.
Emails will have typos in them for the same reason
Emails may also have strange words in them due to the auto spell checking.
It’s my way of saying ‘here’s my quick response, reader be aware’
