Dolphin Browser, the popular Safari alternative listed as an essential app in our Best Web Browsers AppGuide, has just received a significant update.

Specifically, both the iPhone and iPad editions of Dolphin Browser have just been updated with pretty much the same set of enhancements.

Dolphin Browser for iPad, in particular, has been updated with a brand new design and a new annotation feature. The former lets you share, save, and send Web content easier, while the latter lets you draw your own comments or pictures on a webpage for sharing.

Beyond this couple of iPad-only improvements, the separate updates for Dolphin Browser for iPhone and Dolphin Browser for iPad bring the same welcome changes.

There’s one-tap share, which lets you directly share webpages via Twitter, Facebook, or email. There’s “Remember Everything,” which lets you save a Web contact directly to your Evernote or Box account. And then there’s Wi-Fi broadcast, which lets you instantly share webpages with others through a shared Wi-Fi connection.

But perhaps the most notable among Dolphin Browser’s new enhancements is Dolphin Connect.

Provided you have installed the Dolphin browser extensions on your computer’s Chrome, Firefox, or Safari, you can use Dolphin Connect to send and sync. That is, you can send different types of Web content between desktop and mobile, and you can sync bookmarks, tabs, history, and passwords across your devices.

Compatible with iDevices running iOS 4.3 or later, the new versions of Dolphin Browser for iPhone and Dolphin Browser for iPad are available now in the App Store for free.

Along with the obligatory bug fixes, the newly updated apps also include a new setting to open to the home screen or to all of the tabs from your previous session.
