Tumblr has launched a major update to its iPhone app that allows users to update Tumblr blogs with photos, audio, video or text on the go. Tumblr 2.0 has a new user interface with improved views for editing, posting, and browsing posts. For instance you can now edit posts in landscape mode.
There’s also now support for reading and replying to messages from the iPhone app. You can also now sign up for Tumblr from your phone — no computer required.
The new app will also let you find followers from your iPhone’s address book.
Tumblr 2.0 is available as a free download from the App Store.
