iMessage - why is recently send message dark blue?
I just noticed that a message I've just sent to a friend has a dark blue background, while earlier messages are a distinctly lighter blue. Is there some significance to this? This isn't happening with the replies - they're all the same light gray color. Regard:
Notice how the two message at the top (sent a while ago) are light blue compared to the one at the bottom (just sent). Even after 15-20 minutes it doesn't seem to have changed.
