Comment 11 for bug 1270189

@Lorn

It was designed this way in order to make the switching from WiFi back to the mobile data connection fast. Re-working this fundamental design decision IMHOP would be a significant amount of work, and it's not like our current queue of NM related is empty...

I think in the short term if we're able to dedicate cycles to this bug, the best approach would be to re-work how DNS is handled when WiFi is enabled and mobile data is active. My gut tells me that instead of just adding the new DNS servers when WiFi is enabled, that we remove the existing name servers, then re-add them *after* the WiFi nameservers.

Also, I'm not sure that mobile data is needed for downloading HERE/AGPS data, this is something we'd need to discuss with tvoss. That said, it *is* required for MMS to work properly.
