"A new piece of iPhone hardware seems likely to take center stage tomorrow as well. Details of such a device (or devices) have been trickling out over the past few months. It now seems fairly likely that the device will look similar to the current iPhone 3G, perhaps with a different, more matte-finish back and a loss of the silver ring that goes around the screen now. It will likely feature a better camera — probably 3.2 megapixels (as opposed to the current version’s 2 megapixels) and could have autofocus. The device should also be able to record video. It’s also possible that it could have a front-facing camera, though that may be saved for a future version rather than this one. Speed will likely be a focus as the device should have a faster processor, more RAM and be able to handle faster 3G connection speeds. And that leads to two final rumors: The device’s name and battery life."
"The other juicy tidbit in Gruber’s predictions is that he’s heard this new iPhone 3GS will have 15 to 20% better battery life. If true, that is awesome. I recently complained about the diminishing battery life of my iPhone 3G, but when it was still young, I found the device’s battery life to be pretty good — not great, but good, considering how much I was using it. But a 20% boost on top of that would be most welcomed."
