How do I send messages to buddies who use MobileMe?
To start a conversation with a MobileMe user, tap the IMs button and then tap the new IM button in the upper right corner of the screen. Enter the user’s MobileMe name (e.g., example@me.com) in the screen name field. You can also add MobileMe users to your Buddy List view by entering the name in the Add Buddy panel. You can also specify a nickname that will be displayed in lists instead of the user’s MobileMe name.
