That is simply not true.
There are 100's of phones for the European market that are GSM900/1800 only.
Triband phones are more common than they used to be, but it's not 100% accurate to say that they "almost all have 1900", in the OP's case for example, her phone is GSM900 and 1800 only.
In fact, on the CallYa page of Vodafone.de there isn't a SINGLE phone on sale that does more than GSM 900/1800.
There are even plenty of examples of things the other way around with some of the prepaid phones on Cingular, that'll only do GSM850/1900.
Especially on prepaid phones it is still very common to have a dualband phone.
