I was one of the lucky Vodafone customers - had mine after they got their first batch in.
However I think that was only because I phoned up and just continously hassled some poor girl until she said "OK, I've allocated some stock to you - you'll get it tomorrow" - bless her!
It's worth the wait, but Vodafone staff seem to be telling different people different things.
There I was calling them up, being told stock had literally just arrived and I now had a phone allocated to me.
Others were calling and going online and being told at least a week to wait.
