The application file for Samsung's "S Voice"
Siri clone interactive voice assistant agent was leaked over the weekend, leading to hundreds of less scrupulous users picking up the apk and installing it directly on their phones. This lead to owners of any Ice Cream Sandwich device being able to use the service intended only for owners of Samsung's next flagship phone, the Galaxy S III.
However, today it seems the pre-release fun is at an end, as Samsung appears to have locked down S Voice and prevented the leaked APK from connecting to its servers. This means any query sent to to S Voice on a non-Galaxy S III device will return a "network error" message, as you'll see above. (Funnily enough, Apple did the exact same thing when Siri was initially hacked to run on the iPhone 4, so no huge surprises there.)
So that's that. If you want to publicly embarrass yourself by shouting "Hi Galaxy" into your palm, you'll have to wait until the official launch of the Galaxy S III, which takes place in London next Tuesday, May 29.
