Be-Bound is the great world changer of the startup competition at LeWeb. They propose a smarphone app that relies on the standard mobile phone networks to allow for Internet use. How do they do it? By sending sms to and from their servers.

To use it you buy prepaid credit and every action (reading an email, forwarding a message, updating your Twitter timeline), costs from one to three credits.

This application can really be useful on areas with no data coverage and for people traveling to other countries that don't want to pay the hefty roaming data fees. They have already negotiated the access to all mobile networks in the world.

Albert Szulman is the president of Altheia, the company that has developed it.

Update: they did make it to the final (the only company of the three I chose) but ended up second, in a decission critiziced heavily by the jury members themselves.
