Waiting for Major iPhone Enhancements

While the iPhone does many things better than the competition, there are enhancements that would allow Apple maintain its spot at the top including updates to the Phone, Settings/General, Mail/Safari, Clock/Calculator/Notes, YouTube/Maps, Stock/Weather, Photos/Camera, and Text/Calendar applications.

It is surprising how quickly 3rd party developers have been able to create applications for the iPhone. The most amazing thing being the fact that they have done so without an official SDK, documentation, or support from Apple. With this in mind I question the speed at which Apple has enhanced their own iPhone applications. Apple developers should be able to crank out fixes and enhancements -- seeing as they likely employ the most experienced iPhone developers in the world!

Do you think Apple has put enough of a focus on the continued improvement of the iPhone? Does it seem like the firmware releases should include more fixes and features? Which software updates are you hoping for in the next release?
