Just like Android, Dolphin for iPhone features:
- Webzine - a cleaned up news feed, which can pull from any RSS source, Facebook or Twitter
- Gestures - easy navigation to your favorite sites (and showed off nicely in the video below)
- One-click share via Twitter/Facebook.
- Speed Dial - your favorite sites on the go with one touch.
- Tabbed browsing.
- SideBars - easy access to bookmarks, history and more
- MenuBar - access to settings
- User agent - switch between desktop and mobile site formatting
Dolphin is a solid browser, and definitely worth a look.
