Anyone who has used an iPad or an iPhone for email probably knows that the devices automatically add a signature, "Sent from my …" and identifies the device you sent the email from. It's nice for some. For instance, if the editor shoots someone an email, and it says "Sent from my iPhone" we are 90 percent sure that he is out of the office.
However, some may not like that. Luckily, you can remove that or change the message. Here's how:
Settings > Mail, contacts and Calendars > Signature
From there, you can type in any message you want. Pretty nifty, eh?
