Awesome new calendar app for the iPhone. Boils down the calendar to exactly what you need, viewing and quick adding, with alarms. Great little app (syncs with your Calendar that is on the phone already), a bit annoying that you can’t change the calendar that you add a new even to (uses the default only), but it is going to replace my calendar in the iPhone dock, from the developer:
Add an event in just two quick taps. See how full your week or day is at a glance. It works with the built-in iPhone calendar but it’s faster.
