Here's the latest update on what we know about this bug.

First, we have working fix for ofono's behavior when a
DATA_CALL_LIST_CHANGED message is received with an empty call list, and
the context stays active but becomes stale/non-working.  This should
land in a silo by early tomorrow.

Second, Alfonso has pointed out that there may be additional network-
manager changes required.  His original testing performed on
krillin/vivid, and as there's still a race between the disconnect from
ofono, and NM changing the default route, it's still possible for an
error to be thrown when NM configures the default route for the modem.
When this happen, NM leaves the connection in an inconsistent state.
When he tried the same scenario on krillin/RTM plus the patched ofono,
it worked.   I believe he may have just been lucky, and the disconnect
happened before the default route logic ran.  This is a guess, so we
have some more work to in figuring this out.

As these fixes are critical enough to warrant a hot-fix to RTM, we're
going to concentrate on it first, and then address vivid.

  Leaving Wifi does not connect to mobile carrier data (GSM)

Bug description:
  After leaving my home or work wifi, my Bq phone cannot connect to the
  data from my mobile carrier. The only thing that works is rebooting
  the phone.

  Steps to reproduce:

  1- Connect your phone to password secure Wifi.
  2- Suspend phone.
  3- Leave wifi area and resume phone
  4- Wait for 3g data to kick in (appears 3g indicator instead of wifi)
  5- No connection established. I have waited for more than 30 mins.

  6- A reboot of the phone fixes this issue.

  Really annoying to have to reboot phone 3-4 times a day.
