Jobs - With iMessage, we've created a new messaging service for all iOS 5 users. You can send unlimited text messages via Wi-Fi or 3G from your iPad, iPhone, or iPod touch to anyone with one of those devices. iMessage is built into the Messages app, so you can send, text, photos, videos, locations, and contacts. Keep everyone in the loop with group messaging. Track your messages with delivery receipts and optional read receipts, see when someone's typing, and enjoy secure encryption for text messages. Even start a conversation on one of your iOS devices and pick up where you left off on another.
Just gorgeous. Taking the one flaw of BBM and eliminating it in one fell swoop. My only concern is that it's going to be insulting to exclude someone from your read receipts. If that becomes the culture then the feature is moot. On the other hand, is it going to be creepy to ask for read receipts? How are two iOS 5 users going to decide on what's suitable for them? Either way, it was a nice duel blackberry. You showed heart.
