Yes a "watchman" script would be the solution to make the GPRS connection more robust, but this is really beyond my skills. Before I got my first N900 I was pure windows _user_ so any scripting I do with maemo is purely copy paste from someone others scripts. Rarely I'm able to modify/troubleshoot them with the aid of search/google. The modification I posted to Viqsis script weren't mine, I copied them from previous post and posted them so someone could verify I understood the changes correctly, because the syntax of script wasn't obvious to me.

Well I think this means that when I have next spare hour or a day, I'll start learning more about scripting in Maemo/linux enviroment.
