Two nice features of iPhone 3.0

I have been playing with the iPhone 3.0 software on my iPhone 3G for a few days now.  I have seen two features that I think are the best additions, that haven't really seen mentioned other places.

1. Sending SMS messages now happen asynchronously.  With this change you don't have to wait for a message to be sent, before typing the next message.


2. The ability to send a contact to someone via email.  This attaches the contact information to the email as a vcard.  This makes many of the third party contact sharing applications not necessary.
