No luck (yet) for me. On June 23rd, the Service Center pushed 2.24.78 to my car when it was in for something else, and that's when the terrible 3G dropout trouble began for me. It had always been rock solid for the last 3.5 years. On July 26th, I got 2.28.60 over the air, and the problem persisted. On August 5th, the Service Center pushed 2.28.75 to my car and it is as bad, if not worse than ever. Just today, I had 4 dropouts in about an hour of driving. Each time it took about 10 minutes to come back, so in that hour, I only had about 20 minutes of actual connectivity!
