I think I might just have to show up brieflly with BlackBerry in hand, testing "web sites optimized for iPhone" just to make sure they degrade gracefully and checking them overall POSHness .
@tantek: exactly. The whole point is to push the open web as the iPhone platform! No proprietary technologies needed (read: Flash -- hardware is another issue altogether!).
@tantek, @factoryjoe: I may do the same with my SideKick. It's amazing how many sites could easily but don't work because of some sort of optimization. I don't need mobile web, just don't break unnecessarily.
