You can't buy a Galaxy S 4 just yet, but you can have a peek around its firmware, which has leaked online, including those nice-looking wallpapers and ringtones.
It's not quite the same thing as having Samsung's latest heavily hyped phone actually in your pocket, but SamMobile reports that the firmware has leaked online. That's useful right now for those who want to tinker with the core ROM files for future custom builds. It also means that anyone who wants the APK for S-Voice, the custom wallpapers or ringtones, or anyone strange enough to want to watch the demo videos again can do so at their leisure while we wait for the actual phone to be released.
