Pauses in phone numbers and signature lines?

chief_arktk

Two basic questions:

How do I insert a "Pause" or "Wait" character in my phone numbers. The P and W from my standard phone is no longer recognized by my Razor M.

I use Gmail and sometimes reply via my phone - do I use a special signature account in Gmail that says "sent from my phone" or is there a more automatic method that recognizes I'm sending from phone (or tablet...).

Thanks in advance!
