Sony has introduced WebSDK – a suite of mobile development tools that allows both web and mobile developers to create applications for Sony Ericsson devices based on Google Android and Symbian OS. The WebSDK was created in collaboration with the PhoneGap open source community and will initially allow app development for Xperia X10 and Satio handsets.

“With the Sony Ericsson WebSDK our focus is on bringing all the capabilities of web technologies to mobile applications and giving web developers wide access to easy-to-use tools and mobile phone platforms,” says Christopher David, Head of Developer and Partner Engagement at Sony Ericsson. “We are driving this initiative together with the PhoneGap open source community and invite developers to join us as we offer advanced mobile devices and a clear monetization path.”

Sony didn’t give any other information about the new WebSDK, but the main question is do we really need another SDK. Google Andorid and Symbian offer their own SDKs, adding one more SDK to the mix will only confuse the developers and customers.
