The code supports just returning all three values. Parsing just <stat>
is easy but I haven't seen such behaviour yet. On the other hand we
always set extended status, so we shouldn't get short form.

Daniele discovered also problem with SE which revert byte sequence for
either LAC or Cell ID.

No, why?

Not for the network information. For the cell broadcast messages.

That's correct.

No. Cell broadcast is completly different thing. Please refer to
