Hi,

I recently ran across this comment in the org-mode survey:

> I'm on the lookout for a cell phone that runs Emacs, but… I haven't
> found any mechanisms for remotely adding/editing timestamps,
> changing the state of TODO items, etc. Neither have I found a way
> to trigger reminder sounds, e-mails, phone calls, or IM messages.
> I'm not sure about the best way to approach "mobile org-mode"…
> A web-interface like Webjimbo? More robust import/export/sync to

After reading that comment, I wrote cellphone.el that makes it possible to
actually do stuff in emacs on your cell phone.
I have a cell phone with a ssh app, a (very) small qwerty keyboard and
left/right arrow keys, but since there's no Ctrl or Alt keys, working in
Emacs is a pain (every time you need the Ctrl key, you need to go through a
menu). cellphone.el works by setting up several "cellphone keymaps". Each
cellphone keymap binds the letter keys a-z to commands of your choice. An
"orgmode" keymap is included as an example. You can easily select the keymap
with left/right arrow keys.

Please let me know your opinion about the script, as well as any tips of
getting more productive with orgmode on your cell phone.

The script is attached.
