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.

- Status changed from New to In Progress
- % Done changed from 0 to 80
So far I see the following problems
- ran changes 2g/3g (patches in gerrit, but WIP)
- Iu release (patches needs to be merged)
- synchronize PDP Context: MS state with SGSN state (already merged)

So, I learned that the crash is known and comes from changing from 2G to 3G.
Taking care not to do that, I tried the 3G IuPS successfully.
I actually don't see the weird behavior that made me create this issue originally.
It seems that the cause making the IuPS data uplink hickup has indeed been fixed.
lynxis from my side it seems that we can close this, and track the remaining known IuPS problems in their own issues each. Agree?
