Android: Smart Browser Chooser is a simple application that toggles your browser based on the network you’re connected to–automatically switch to an optimized browser for lower data usage when you’re on your mobile data plan.
That’s the principle reason most people will use Smart Browser Chooser; it allows you to set a browser with lower data consumption for the times you’re on your limited mobile data plan and a different browser for when you’re on a Wi-Fi network. When you’re on a wide open Wi-Fi connection, for example, you can load up DolphinHD and then when you’re out and about, relying on your limited mobile data plan, you can switch to a lighter browser like Opera Mini.
Smart Browser Chooser is a free application, requires Android 1.6+.
