How do I remove/edit the 'Sent from my iPhone' signature from emails sent from iPhone?

By default, when an email is sent from your iPhone, a “Sent from my iPhone” signature will be added to your message.

To edit this, follow these easy steps:

• From your iPhone home screen go to the Settings menu.
• Tap Mail.
• Select Signature.
• Modify the signature for all mail accounts you have set up, or on a per-account-basis. If you wish to have no signature, delete the entire text.

When ready, tap Mail in the upper-left corner to save your changes.
