The popular Dolphin Browser for Android and iOS has been updated today to introduce a number of handy new features. In addition to one-tap sharing to Facebook and Twitter, users can enjoy Evernote clipping, and the ability to sync bookmarks and tabs between Dolphin and their desktop browser.

Late last week, Instagram — now owned by Facebook — confirmed it had disabled Twitter integration, and the ability for users to see Instagram “cards” or previews in their timelines. While it’s not a massive issue for Twitter users, who will still gets links to Instagram photos, it marks the first major breakdown between the two social services since the Facebook acquisition.

But things could have been very different. Weeks before Facebook bought Instagram, Twitter was close to acquiring the photo sharing service for just $525 million.

Twitter has unveiled Instagram-like photo filters for its official mobile apps on Android and iOS. It’s been rumored that Twitter would roll out this feature by the end of the year, and the time has come.

You can choose from 8 basic filters and crop/enhance your pics before sharing them in the Twitter app. This addition comes after Instagram recently shut off photo previews for links shared in Twitter.

A big Instagram update is now available for Android and iOS devices. The camera interface of the app has been improved with a quick preview of the last picture you took on your device. Now there’s an optional grid guide for taking pictures and a permanent grid to help you with aligning when you’re scaling and cropping. For iPhone 5 users, Instagram has included an “improved Camera Roll image selector for quick access to your last photograph.”

Today’s update also includes a number of speed enhancements, Foursquare buttons, several design tweaks, and a new filter called “Willow.”

This isn’t going to happen.

Nokia set the rumor mill alight last week when it posted a job listing on LinkedIn that called for a senior software engineer with Linux experience. Many felt it was an indication that the Finnish firm was experimenting with a Linux-based platform — such as Android — for a future smartphone.

Nokia has since clarified what the job listing is all about, however, and although it hasn’t completely denied working on an Android smartphone, it has all but killed the rumors in relation to it.
