After a week with the iPod touch here is what I have learned. Keep in mind I have a first gen model with the 2.1 upgrade. This stuff is probably documented somewhere but I generraly skip the dogs.
While using mail, if you swipe left on a message in the message list you are given the option to delete it.
While in any app you can double tap the home button to get a volume control and ability to pause/play or skip tracks.
The keyboard will auto correct a lot of things yet it can’t spell check.
I think that is it for now. If there is something you know about that I didn’t list here leave iron the comments area.
