Tumblr has updated its app for iPhone and the iPad to version 3.3, bringing several nifty updates, including a new camera app.
The camera now has a grid, flash and the ability to create photosets straight from the app.
Other improvements include double-tapping posts to like them and tapping the avatar in user profile to change it. Also, if you copy or enter a URL into the app it will automatically fetch the title page.
The new Tumblr iOS app is available here [iTunes Link].
