I've got the same issues as most, but like the majority of us we are working through them hoping for a fix. I have one particular phone number that if I receive a text from I can't send a reply back to that number. It says code : 0 Bad Phone Number.......if I send a text, like sending a new one all together, it works fine. It is only on this number it does that. I have tried deleting the contact and re-entering but it does the same thing. Any ideas?
I still am running 2.1 by the way.
