As far as I can see it, sms is way more used then calling in the
private field, but calling is more used in the buisness field.

XMPP (ex Jabber) [1] gives the possibity through so-called "gateways"
to talk to other services. I for example talk through jabber to my
friends in icq, in msn and in yahoo talk. But, like the article says,
xmpp has even the possibility to combine im and sms. Having such a
system on a phone shure makes sms obsolete.

That's really true. And sad. But a system like the one used by XMPP,
just in the voip field (I think even XMPP is going that way), would
really make the pstn obsolete. And even more: voip has often the
possibility to make calls to pstn and recive calls from it: so if a
phone is equipped with a gien voip system fine, else you simply call
the pstn network through the voip system.

I don't know about this, but it sounds intresting..

That's often the question, and if companies like OpenMoko become
known, the possibility of having an Open Source implementation also

I also would say that I don't know about Stefano, but i thought of
this as a modular system when I read this mail: If you feel the need
for gsm you put in the gsm module, if you think oyu need 4g you put in
that chip, and if you think you need something else, then simply use
something else. Doing this way you, for know, you simply creatre the
gsm module. Then you create some 4g module, and people can buy it,
upgrade their "phone", put it in a new barebone system, or whatever
they want. Having a modular approach gives true freedome, in my
