[Preroll]

Not very important but I thought I'd ask. I received several text messages the other day. These messages were sent to a group of people (me included of course). One came in from the sender as yellow and the other as a light purple. Normally if it's just to me it's light blue. So, the only difference between the yellow one and the purple one is that the yellow one included everyone within my contacts list and included a picture. The purple one was text only and included some recipients in my contact list and the rest were not.

Again, this is not too important but it struck my curiosity. Obviously an OS7 feature of some kind that I haven't been able to find.
