The iPhone 4S antenna Antennagate rocked Apple's world for the wrong reasons after the launch of the iPhone 4, so we were keen to see how the new design 'improves call quality' and 'reduces risk of dropout'. Both the 4S's antennas, which run around the top of the phone, can transmit and receive data, allowing for faster 3G connections. Apple claims that maximum download speed over HSDPA is 14.4Mbps – twice as fast as the iPhone 4. In the few days we've been testing, we haven't noticed an improvement in call quality and didn't experience any dropouts. But we have definitely seen faster download speeds over 3G and quicker web page loading. T3.com took an average of 5 seconds to load on the iPhone 4S, compared to an average of 8 on the iPhone 4. We also ran the SpeedTest app (on O2-UK network) and got an average of 3.34Mbps download and 1.45Mbps upload. On the older iPhone 4, on the same network in the same location, we achieved average results of 2.32Mbps download and 1.31Mbps upload. We also tried the death grip (for old times' sake) and didn't see any signal bars dropping off a cliff. Hurrah.
