I just noticed that text messages I sent today have a d over the check mark next to the sent message....Today is the first day this appeared....what does it mean????
Now that I'm at my regular computer, I wanted to address what you said about this just appearing for the first time yesterday ...
I remember not getting the delivery confirmation for everyone I texted. I think I only got it for contacts on Verizon.
You can disable this in Options/SMS, if you wish, but it's one of BlackBerry's great features.
