Just take the phone number from the arrived text message, map it to the stored image of the sender and other recently received messages from him, create a new screen with pictures displaying continuous conversation.
Looks simple but very effective – this way you can quickly identify the sender, follow conversations with different persons just like in IM chat client and significantly reduce the number messages to the wrong recipients.
And it doesn’t need the latest Core 2 Duo chip or programming genius to be implemented. Expect for this feature to show up in new Samsung phones pretty soon.
I love it. Threaded SMS just makes so much sense. Adding avatars is just another evolution of that idea.
