How do I limit how long emails stay on my phone? Before the upgrade in October, I could limit how long emails stayed on my phone. After the upgrade that limit disappeared. I now have over 600 emails on my phone and no way to get rid of them all. As soon as I delete, say, 50 messages, the phone downloads another 50 from weeks ago. All these emails have slowed down my phone. How do I get rid of them???
