Yes, I've been in London for the weekend. I bought a 1 week
international data flat. Anyhow, I can still reproduce this 100% now
that I'm back home.

Looks like the times I entered metro stations :) So yes... Basically I
had to reboot every time after I exited the metro, because cell
reception dropped, mobile data disconnected and wouldn't reconnect until
rebooting.

yep, exactly.

Yeah, I think I tapped that in order to force the list to update as it
wouldn't show the hotel network for a while after being back in the
hotel. But that's a different (not so critical) issue.

Can't judge that. Please let me know if I can provide more
logs/details/testing. We really need to get this nailed down as it's the
most important thing on a phone after being able to do voice calls.

  Phone not connecting to mobile data until rebooting

Bug description:
  Whenever I walk out of WiFi range, my phone does not connect to mobile
  data. Toggling flight mode does not help. I have to reboot the phone.
  When then I finally manage to connect after rebooting, if the signal
  strength drops and the phone would want to switch from 3G to 2G, it
  disconnects and I have to reboot again to get mobile data.
