Dolphin Browser comes to BlackBerry PlayBook
Because of that, the browser has been said to lag and slow down at times, but the features should be close to what we expect. Just like the Android version, the PlayBook variant features gestures for easy navigation, the Webzine and Speed Dial UI for getting to or seeing content from your favorite sites, as well as tabbed browsing and the Dolphin sidebar.
It may not be perfect, but it should be better than the stock PlayBook browser, and it is free. You'll need to have updated your PlayBook to version 2.0 of the PlayBook software, and then you can grab the Dolphin Browser in the BB App World.
