[Tony Espy <1378102@xxxxxxxxxxxxxxxxxx>]

I totally agree with Mathieu's previous comment.  This has been
discussed before, and all parties had agreed that the most pragmatic
approach to this bug at this point in our cycle was to simply have the
APN editor disable the current context before activating a new context.

Changing this in ofono requires a change to the core ofono GPRS
behavior.  Some modems allow multiple contexts to be activated.  In our
case, as we only allow a single Internet context to be activated and
indicate this to the ofono core, when a second context is activated, the
error NotImplemented ( which I agree is a poor choice ) is returned.

I'll add an ofono task to this bug and set it's importance to wishlist.
The desired behavior change is something that we'll need to discuss with
upstream.
