It also seems odd that these phones didn't have their time adjusted
as a result of receiving NITZ messages from cell towers with the
correct UTC offset.  I thought that using time and timezone
information from the cell network was the typical default
configuration on smartphones (which makes having an up-to-date
timezone database less critical).

Are there carriers in Israel that don't broadcast date and offset
information from their cell towers?  Or were the carriers
broadcasting incorrect data?

http://en.wikipedia.org/wiki/NITZ doesn't have information on
Israeli carriers, but it also suggests that there are substantial
numbers of mobile networks that don't provide timezone information.
