In the documentation, it's note that we can do the update by ourself with our phone via a gprs connection.
It's note that to do it, we havec to push Main/configuration/update But in my case I don't have this last main : update

At the end it's note that in some case, this functionality is note installed and we have to update the systeme...

It's why i wanted to know where I can found this update... Of course my seller have it, but, can I found it by myself? After I think it's very easy

Thx
