Until now, the best way to install Siri on iOS devices other than iPhone 4S has been Spire, a jailbreak tweak released in December last year that requires users to connect to a proxy server to let Siri respond to users' commands.

Thanks to a Vietnamese Dev team, the users now can install an apparently much more advanced alternative to Siri, called Sara, in all iOS devices.

According to App Advice, the app offers a number of features and overcomes several limitations that Siri has. For instance, it works in a variety of countries apart from the U.S. and Canada. In addition, the app is available in over 37 languages.

Sara can also reportedly control PC, switch phone toggles on and off, search for songs and scan barcodes. It can even learn from its mistakes and does not need any proxies to get the tweak up and running.

To use the app, users need to add http://isoftjsc.com to the Cydia source list and download the version specific to their device.
