Lots of nice specific suggestions and examples to align the look of the layout with the iPhone UI generally. IMHO your post could be prefaced or ended a bit more tactfully (people are generally more likely to be willing to consider feedback when they feel respected). I have to say though that for me most of the suggestions seem in the right direction. You've got a good eye for this stuff and a knack for being helpfully descriptive.
