How can I get Linux on a T-Mobile phone?

     I have an old T-Mobile Dash cell phone.  I want to run some form of Linux (or another open-source OS) rather than Windows Mobile.  I want to be able to do open-source voIP, text, etc.  I also want to be able to use T-Mobile's supposedly excellent international coverage (I'm going to England).  The phone can connect to a computer and has a microSD slot.  Any recommendations are welcome.  Thanks!

P.S.  I heard that I could partition off part of the microSD to use as extra RAM.  How do I do this?

I'm also thinking of toughening it up to survive drops, falls, water, etc.  Any recommendations as to what to do for that are appreciated.

I'd be really surprised if there was an open-source retrofit for older phones. Delighted, but surprised.
