The freerunner is a phone capable of running Debian and Emacs!
FsoEl is a project to create an Emacs interface for the freesmartphone api.
Here are some other ideas:
I really think Emacs could be a superior telephone application plattform!
If you are using Debian on your freerunner, installing emacs is just a question of
aptitude install to install Emacs. However, it is well-nigh unusable even with the full keyboard.
The default usability of emacs on a tablet like device is indeed somewhat lacking, but this is mostly due to default event bindings not being entirely suitable. This is fixable, for instance with tool-bars(Ive contributed patches for emms and planner) and with the “symbol chooser” described above(i have some code for this also) --JoakimVerona
I have written a couple of libraries for sending SMS text messages in emacs: Lisp:sms.el and Lisp:bbdb-sms.el. I use them on my Android phone, but you just need to alter a single function to get it working on other devices – JoeBloggs
