I would really love someone to come up with a modification to the existing email application that allowed us to put signatures (e.g. "sent from my android mobile device" or something similar) using the default email applications (I don't want to have to resort to K9 or Touchdown to get this functionality).
Issue 4588 - android - Email app should allow automatically adding a signature over Exchange - Project Hosting on Google Code
illustrates the frustration that some business users are having with the Moto Droid. If anyone comes up with a patch to the existing email application, I would really love to have it. Thanks for reading
