i\’ve a Blackberry Bold 9000. It holds a good bunch of text messages, but how do I regulate it to keep messages through different people, while deleting old messages through people, rather than just deleting text messages based on time received. I’m having a problem with a few people texting me a lot and I’m losing messages through people who don\’t text as much, but are still important messages. Those who don\’t text as much are being deleted based on age.
