Following a closed beta late last year, Sony has made available the Playstation Suite SDK to the global audience. The suite allows developers to build apps for Playstation Suite certified devices like Playstation Vita, Xperia smartphones and tablets.
The beta download is provided for free and allows developers to build and test their apps before submitting them to Sony. Sony also made available a set of tools and libraries to help get developers started.
The final SDK will arrive later this year and Sony will charge an annual fee of $99 for developers that want to sell their apps on SEN.
