By the way, the gprs atom is meant to be put into the post_sim phase now.

I still don't see how it can not change.  If you go offline you should 
be detached and only attaching once the gprs atom tells you to.  I 
presume the PSNT will change during / after the attach procedure 
completes, not before.  That means just the URC is enough.  Same with 
sim change, etc.

Lets get a version of this patch upstream without the query.  If you can 
show that we still need to query then I have no problems pushing that 
afterwards as well.
