We already told you guys about the Developer's Edition of the T-Mobile G1, but what if you already have a T-Mobile G1 but want the Developer's benefits? Well, first off, you have to thank the hackers. Apparently, the bootloader for the Developer G1 has been extracted and is now available to anyone who's daring enough to use it. Basically, get root access and apply the bootloader. If you do mess up any steps though, beware, your phone may be bricked.
The benefits of running a Developer's Edition G1? Well, you can potentially mod it like crazy!
