Samsung Galaxy Nexus — signature in Galaxy Nexus

Hi,
Maybe this post is a little stupid but please bear with me.
My friend she sent me an email from her Galaxy S3, and her signature 'sent from a samsung mobile', was in a different color very much distinctive, so I was wondering if I can do the same with my Galaxy Nexus
She used Gmail if you are asking.
Thanks in advance
Cheers

I havent found a way to do this. Perhaps your friend has a rooted device and is using a mod?

It could also be a Touchwiz feature. I will look to see if there is a way to do it, but I have never heard of a way to do it for the Nexus.

Thanks for your answer.
She doesn't have have a rooted phone, I know that for sure.
Maybe it's the touchwiz thing, but it looks very nice actually.
The words : Sent from a Samsung Mobile, were in light blue and the whole sentence was faded out in a nice way

I have the Galaxy SII and whenever I send an email from the default email client, it adds "Sent from Samsung Mobile" at the end of the mail. I haven't found a way to change that other than deleting the sentence when I write a mail, nor have I found a way to customize the message. It may be a Galaxy SIII feature that's not available in previews models like my S2.

Why not ask your friend?I have seen the conditions in some forums but I haven't seen the signature in this forum.
