some stupid question: if a phone does not support any encryption, is it possible to use it on an official GSM network? (authentication works, of course) if so, what phone might it be?

I did a quick check, at least Vodafone and T-Mobile here in Germany reject the Location Update Request with "Network Failure" (0x11) if they get a classmark without any encryption available. The registration works with the same phone if the classmark indicates that encryption support is available. The test was done with a phone where I can modify the classmark data.
