This has happened twice already, sometimes when I'm texting or using my phone I go back to the messaging inbox and all my texts get deleted and the only things left in there are my email. How do I prevent it from happening?
It not that you don't have enough specifically. There is a known memory leak problem. So make sure you are hitting menu close and not backing out of the applications. Move all media to your media card and reboot at least once every couple of days.
