This morning I noticed that Apple released iPhone OS 3.1.3 through iTunes, and it includes the nice feature that the battery monitor is supposed to be more accurate - which is good, even if the time I can use it is shorter. I need to plan what I can do with my phone, and this is just essential information to that planning. There were other security fixes, which is great, and I was always going to upgrade, it's just nice to know what it was about.
