This is a most excellent place for technology news and articles.
But do carriers really have a horse in this race? SIMs are separately secured so all they care about is having as many in use as possible. Whatever game of cat and mouse manufacturers choose to play with the users is their business.
I don't think carriers will want the headache that comes with SIMs checking if they're used on so-and-so devices, especially if it involves depending on a service they don't control (like Google).
Yeah, carriers want as many user as they can on their network. So no valid reason to block a user if they root their phone.
