Have had the 3G for the last year and just got my wife a 3G S this week. I absolutely love the phones and applications that I can get along with it. However, I am near the end of my rope on dropped calls. I would estimate that at least 25% of my calls end up being dropped at some point. Was hoping the 3G S would be better but alas, 2 of the first three calls my wife place were dropped. I'm just trying to figure out if this is just a result of AT&T or the device itself. I've done all the updates and like I said, my wife's brand-spanking new 3G S is doing the exact same thing. I'm in Chicago. I swear if I get one more "Call Failed" message my phone is going to end up in the Chicago River.
