layarLayar, the augmented reality browser for mobile devices, has just released a new version with some huge API improvements bringing it’s functionality to a whole new level.

With version 2.0, Layar has given access to its API to 500 more developers, which are currently developing more content layers. Having Twitter or Wikipedia info layers on your phone is nice, but Layar is going to need support from many more developers if the application is to become really useful. Current partners also include Brightkite, Yelp, and Trulia.

Still currently only available for Android devices, but an iPhone 3GS version is in the works.
