Every iPhone owner has one; here’s mine.

• BCC ability. I don’t understand why this isn’t an option already. This is fairly standard on every email program I’ve ever used.
• Distribution List ability. Mail/Address Book on OS X supports distribution lists, but not the iPhone. This one baffles me as to why it was omitted.
• Mulit-client chat (YIM, AIM, Jabber). Not very important, but would be a very cool addition. If added, I just hope it’s not limited to AIM.
• Contacts having own home screen icon - Address Book. It’s an annoyance that I have to enter the Phone app to get to my contacts. Seems an Address Book option on the home screen makes too much sense.

I realize that Apple didn’t want to miss the June deadline, and I appreciate that. Hopefully these features and more will be added in the near future.
