SMS is broken after updating to 2.1. I have also confirmed this on 3 of my co-workers phones. I didn't notice it until I received a few calls from people saying that I didn't respond to text messages. I have tried texting from several different carriers and I don't receive them and when I text to any phones they don't go through. My co-workers have also confirmed this. Restore does NOT help. What should I do? I need text messaging to work.
