If you were dazzled by Samsung's S-Voice from the Galaxy S III in the day or so before they blocked access to the operating servers... then you're probably easily impressed. But for the three of you who have Android 4.0 devices and really, really want a shameless Siri clone, "ithehappy" over at XDA has created a signed APK that fools said servers into thinking you're running the unreleased Galaxy S III without checking the standard build.prop value. Get after it!
The modified app appears to be working on most Ice Cream Sandwich devices, though you may need to make some changes to the permissions in your file explorer of choice. (And let's face it, if you're installing unreleased apps from an upcoming manufacturer skin, you're probably already rooted.) In addition to the modified S-Voice app, the XDA user has posted a sack full of goodies from the phone, including customized apps, wallpapers and ringtones.
The Galaxy S III is set to debut in Europe on May 29th and the UK the day after. If you happen to be in Dubai, you might want to check your local electronics store, as scattered reports say the phone is already on sale in some locations. There's strong evidence that all four major carriers in the US will be getting the device, though dates, prices and exact specifications haven't been nailed down yet.
