Can you explain further? That distinction may be what is intended, but it's not how it's working on my phone. As I said, some threads in which the last message was "sent" are blue, some are white; and some in which the first message was "sent" are blue, some are white; and likewise with threads in which the last or first message was "received": some are blue, some are white, and I cannot make out any pattern at all. The whole thing seems completely random. And, also as I indicated, I've seen almost the entire list of threads turn blue while I'm looking at the app, not doing anything with it at all.

Is this feature available on all Android phones, or just Stratospheres? Ann has never seen it on her Nexus or Thunderbolt, and both of the other two people who do report it have Strats, as I do.
