#2Interesting. I didn't know it was possible, but, seeing as it is an UDP-like unidirectional message and an old system, it isn't surprising.
Wikipedia has more information for the interested[1].

#3You can use this trick to listen to anyone's voicemail (by identifying the calling number as the recipient's number) if they do not have a password. Anyone. Talk about security hole.

IIRC, this same flaw was used by Murdoch's papers to hack various celebrities'/deceased individuals' voicemails.

#5You can do this from any SMS gateway, as there is no real verification. However most gateways do not allow their users to spoof the sender because predictably the carriers do not like it.

#7"Kostnaden för sms:et är 10 kr plus eventuell operatörsavgift."

It depends, many voicemail system require a PIN, especially after some of the recent exploits.
BTW, this is talking about SMS, not CID spoofing, so your comment wasn't exactly on topic.
