If you’re the tinkering type and you’ve been eyeing the Galaxy S 4 on AT&T, you may want to rethink your options. According to Cyanogenmod founder Steve Kondik, AT&T’s S 4 does indeed have a locked bootloader out of the box. While the locked bootloader doesn’t necessarily mean custom ROMs and kernels won’t come eventually, it’s going to take a little longer than usual. Of course, with the inevitable popularity of the S 4, there’s likely going to be a crazy amount of dev work being done on the device right out of the gate, so an unlocking method will likely come along sooner or later.
I don’t expect this to make a huge impact on S 4 sales on AT&T, but for the modding community, it’s a bit of a let down.
