Maybe I'm missing something, but why not just take a minute or two every couple of days and select all of them and delete? I personally use Ms myphone and you can go in and click whichever ones you want to delete or archive ones you want to keep, but IMO, unless I'm missing something (it is early so I'm a little slow right now...) I would just recommend going in, selecting all if you want to delete all, and just delete them from inbox and sent and deleted.
