Sure, the AT&T Galaxy S 4 has a locked bootloader, but that hasn’t stopped anyone. The bootloader was unofficially unlocked, and the phone can now be modified to a users content. But what do you do without source code? Luckily, Samsung released source for the AT&T model today on their open source center, so you can give that a download and start messing with it and making some awesome ROMs for an awesome phone. We hope to see some amazing stuff show up, because let’s face it, software is never perfect. An active developer community guarantees that there is something for everyone.
