It appears that a leaked unsecure bootloader for the Verizon Galaxy S3 (Galaxy S III) has lead to a hack that allows the bootloader on the retail version to be replaced. In a nutshell, this means that developers can now build custom kernels and flash them via Odin, and nobody will need (or want) to buy the developer model when it comes out.
Right now, I would recommend that the average user just sit back and watch. Let some developers worry about versions and wait for the first person to put it to good use -- which will probably be soon. I just wanted to pass the news along, as I know there's a few of you out there that have been waiting. For more details, hit the source link below. Happy hacking!
