Dell D5530 is an OEM version of F3507g. It has an annoying habit of
announcing itself to world with its own name. It also crashes upon
processing received cbs messages.

Should we really bother with this one? Or you're trying to be like
Marcel and waste some processing time with unused unsolicited
notifications? :)

Can you rebase your patch, I get this when applying:

When you have resolved this problem run "git am -3 --resolved".
If you would prefer to skip this patch, instead run "git am -3 --skip".

I'm trying to develop with this fine piece of hardware. First time it
was funny when my IMSI was D5530. Or +GCAP: +CGSM, +DS.

Dell D5530 is an OEM version of F3507g. It has an annoying habit of
announcing itself to world with its own name. Another problem is some weird
+CGAP messages at the same time. It also crashes upon processing received
CBS messages.

I think we should until we have this all figured out. More debug output
is always a good thing.

And yes, essentially there is some processing wasted, but then again,
this hardware is so damn stupid broken it deserves to be punished ;)

I have to disagree, I can understand if you take the unsolicited
notification and break it down somewhat (like we used to with OCTI,
OWCTI, etc for HSO).  But just printing a debug seems useless.

then lets break it down ;)

	DBG("5");
