As with any exciting new flagship device, it was only a matter of time before Samsung's recently-unveiled Galaxy S4 got the system dump treatment. Sharing the goodies this time (having already leaked S Voice, wallpapers, and ringtones) is SamMobile.com, who claims to have an "insider" that provided the leaked dump. According to SamMobile, the system dump is based on the S4's latest test firmware, affectionately called I9500XXUAMCH, built just a few days ago on March 23rd and based on Android 4.2.2 JDQ39.
For those interested, SM also posted the device's build.prop along with a few screenshots.

If you're interested in downloading the full dump, you may want to block off some time – the download is 1549.8MB or roughly 1.51GB in size (over 2.2GB unpacked). That said, if you'd like a peek into the Galaxy S4 for development reasons (or just plain ogling), you can grab the download from SamMobile below.
