Putting hard numbers to the iPhone 4 antenna issue
The discovery that gripping the iPhone 4 in a way that bridges the left and bottom antennas can cause serious signal problems has resulted in—to say the least—a lot of controversy. However, most of the data that either "proves" or "refutes" that existence of said problem has been anecdotal at best.
So AnandTech used a clever hack to get an iPhone 4 to report actual signal strength instead of "bars," giving some quantitative data about how bridging the antennas can negatively affect signal strength. The analysis explains why not all users are affected by the problem, and further investigation also ...
