Re: automatic APN selection

[Alex Ferm <aferm petropower com>]

Hey, just so you know this basically exists. You just need to create a 
connection profiles with the correct "sim-id" "apn" pairs. Some users, 
myself included, wouldn't want this to be automatic because we use 
private APNs, but you could easily put together an optional package of 
connection files that accomplishes this.
