3G IuPS is unreliable
When first registering on a 3G network, IuPS data service often does not work right away.
Going to flight mode and back into the network may resolve the issue. Sometimes it takes several of them.
Once showing a website the first time, it seems to work well further on.

hmm, it doesn't seem so easy to reproduce a situation where the new_key flag reflects the wrong value.
I do get unreliable behavior, like web browser page failing to load, failing DNS lookups on-and-off, but all the while the new_key flag reflects the actual key status that is transmitted.
It doesn't seem to be as quick a fix as I thought.
