Dolphin has been released on Apple's iOS (iPhone, iPod touch, and iPad). It has been available for Android for quite some time and just celebrated over 9 million downloads.
For Android I tried all the mobile browsers and found Dolphin to be the fastest and most stable. Considering their mobile browsing commitment, iOS users can be sure to have a similar experience. With Chrome for Android on the horizon this is a great move to continue expansion.
Download Dolphin Browser from the iTunes store and let us know what you think of it in the comments after you tried it out.
