I think that your concerns about software freedom and privacy are a very good
thing, and you should definitly keep them in your heart.
However, though many people here might disagree, software freedom is one
important thing among many important things in life, and if you feel that not
carrying a cell phone becomes to much of a burden, then I advice to make a
compromise and get one.
You could still try to use as much free software as possible on it, and you
can keep an eye on projects that might help to improve the situation (maybe
also financially supporting them).
I, for instance, have a history in life that makes staying in touch with my
friends extremly important for me. Isolation makes me literally sick. Now,
it's true that a cell phone is not the only way to stay in touch with them,
but nowadays, without a cellphone, the amount of communication will at least
drop.
That's something many people can live with, but I can't. For me, staying in
touch with my friends is more important then software freedom, so I agree to
make this compromise.
The same way, i'm a very chaotic person who has a hard time organizing
things, remembering dates or finding directions, which lead to a lot of
serious trouble in the past. With my cellphone, things are way easier and I
feel that a burden is taken from me.
I don't say that we shouldn't make sacrifices for software freedom, but
everybody should decide on her own, whether the sacrifice is too big or not.
If you push yourself too hard, chances are that someday you might become
completely fed up with the situation and drop your beliefes completely.
