It's rare when an app in the Android Market gets a feature that its iOS counterpart doesn't have (especially a coveted one), but for the past month, Dolphin users on Android have been navigating their browsers with Sonar, the latest innovation for one of the most feature-rich mobile options around. But rejoice, iPhone users – the wait is over.
