I don't doubt that you may be experiencing favorable service. Outages will affect some users differently than others. The rep didnt tell me that the entire AT&T 3G network went down, but rather they were experiencing major outages due to high volumes and issues on the east coast. It still doesnt make sense to me why I would be having so many issues out on the West Coast though, but i guess the only thing to do is sit it out, or return the phone. I was given an account credit due to the issues, but hopefully its resolved soon.
My personal feeling is that the signal issues being experienced now will not be resolved until AT&T can improve their network, or correct the outages effectively. A software update for iPhone4 would probably be worthwhile as well.
so the rep didn't tell you their is a nationwide outage, but you choose to start a thread that says there is one? nice move
