3G Pin question

[van Schelve <public van-schelve de>]

Hi Folks,

we are planning a rollout for a big number of laptops with internal 3G
Datacard.
The 3G configuration is fixed and should not be changed by the user.

After a fresh installation and the user is logging in the first time he
should
add the PIN Number for his SIM Card.

I'm thinking about a xinitrc script or somewhere in gnome presession,
postlogin

What do you guys think about this solution? Any better Ideas?
