Hi,
I have been told that anyone who has a sim card that was bought before June 2007 & is not registered, must be registered before November 9th 2009 or it will be deactivated & will have to change mobile number. Has anyone else heard of this???

yes its true i heard this a while back i dont know the exact dates but its to do with terrorism so phones have to be registered to people ,go to your local shop with your passport and spanish id .
