Delete "Gmail" or rename it - urgent

Hi guys,

in germany when you want to safe for sale an iphone you are not allowed to have the word or pic "gmail" in the Iphone.

Telekom Iphone have a firemware without these Gmal-string and picture.
Sadly the most I import doesn't. So I must delete the chance to create an mail account for gmail or i must rename the "Gmal" to "Googlemail".

Things that work:
- delete the pic "gmail.png" and copy the "googlemail.png" to "gmail.png"

So I only fight with the string, that is shown when you create a mail acc.

I searched a lot but in all *.string files I checked only the placeholder "%@" is there, which will be the word "gmail".

I take all ideas i get, please.
