I habitually disable auto-retrieval of MMS, however I am very much considering not renewing with Verizon due to concerns over the speed of security updates. Considering today's technology, the concept of just upgrading devices over a few months old isn't going to combat the development of these security breaches. I would like to know if there is any official acknowledgement by Verizon and plans for how to roll out security updates for this issue and others, and there will be others without a doubt.
