Here's a to-do for Steve and his team:
1. A mechanism to add additional root certificates to the X509 key store for Safari. Lots of folks use them for intranet stuff.
2. LEAP authentication for wireless. It's what we do where I work. The mac can do it, so should the iPhone.
3. Flash. You're just not going to get your way on this one, Steve. Promise.
4. Voice dialing.
5. Internet IM.
6. custom ringtones from iTunes.
7. A2DP - also known as high quality stereo over bluetooth. Rumored to already be on the way.
