From a client point of view it may look like the same, but from an operator (company) point of view it is different. If I am an operator like Vodafone or ATnT, if the restriction is based on access control, I can change my procedures to permit the usage. However if something is removed based on deprecated, I have no solution. -- Balazs Lengyel Ericsson Hungary Ltd. Senior Specialist Mobile: +36-70-330-7909 email: Balazs.Lengyel@ericsson.com
