iPhone: Change your email signature
Contributed by qmchenry 
Tagged: Apple iPhone The email application on the iPhone has a default signature for all outgoing messages of “Sent from my iPhone” which is convenient on your first day of iPhone ownership since this is likely the email you’ll send to people first. When they new wears off and you are sending emails for reasons other than bragging rights, you’ll probably want to remove or change the signature.
To change the email signature on the iPhone, tap the Settings icon on the Home screen, then the Mail button on the main settings screen. You’ll see a screen like this:
Scroll down toward the bottom and tap the Signature button (where the big red asterisk is on the image above) and the signature editor will slide in as shown below:
On this screen you can delete or edit the existing signature text. When you have it the way you like it, you may leave the editor screen by any means you like. Tapping the Mail button on the top right will return you to the other mail settings and tapping the Home button (below the screen) will take you to the Home screen.
At the time of iPhone release, there is only one signature on the iPhone so it will be used with all of your email accounts. A separate signature for each account would be a great addition in a future update (hint, hint, nudge, nudge).

Good. Now I can add a Blackberry signature. I hate that my company has mandated iPhones and I’m losing my Blackberry.

How can I remove the ’sent from my iPhone’ when adding status in Facebook? Even if the signature is away from my phone, it’s keep appearing in FB…??

I just got my 4 and tried to change the signature — I’ve got it done — it appears in the settings, BUT is not appended to my messages. They still say “sent from my i phone.”
When I access the signature, my custom one still appears … the phone just doesn’t use it.

I think it’s terrible that even now iPhone 4 does not even have a different signature for each account. This is a basic business essential. Very poor.
I believe there are some apps on the store that do this and I guess that perhaps Apple would rather take their cut from the sale of these, rather than add this basic option as standard. Disappointing.
