We complained about our reception, they,apple, replaced the iPhones with new ones. We continued to have dropped calls and bad reception on those that didn't drop. We now have spent the $150 dollars to purchase AT&T micro cell to boost the signal in our house. We didn't need this for the 3GS. Now with the booster, we are still getting dropped calls from the garage which is one room over and down from the microcell. Lastly, we are in the 3G area for AT&T, we did not have dropped calls from anywhere in the house on the 3GS. This is Not an issue the display of strength, it's an issue with the iPhones signal reception.
