The recently released iOS 5.1 beta has just given a new life to rumors mill with the discovery of new references of the iPhone 5, iPad 3 and new Apple TV with A5 processor. It appears that Apple has baked the iOS 5.1 with having plans for the couple of unreleased / not announced services. iOS 5.1 to be the first public iPhone 4S Siri official update from Apple, which fixes the overall performance bugs and includes the new features for the Siri.

As reported by the hackers, the new iOS 5.1 also carries limited Siri API support for developers and enables them to give some Siri love to their applications, as we have already seen the couple of applications with limited integration of Siri into the third party application’s core. The new limited iPhone 4S Siri API’s allow developers to call some functions on their applications but still not allows them to fully integrate it in the core of the application.

In short, the availability of this limited Siri API support in iOS 5.1 beta 1 show that Apple has also been considering to roll out official API system for developers to create their applications according to their Siri feature need, or could allow them to develop such apps, which wake up on the Siri’s API calls. We have already seen the couple of Siri hacks from the SiriProxy, a web-based Siri proxy server that allows users/ developers to generate their own commands on Siri.
