There are plenty of ROMs for the G-Nex between XDA and Rootzwiki, but here's the problem in 2 parts:
1. The device is new, so the ROMs are new, and most are basically the same underneath, just stock with a couple of minor tweaks.
2. When you get an AOSP phone, everyone thinks he's a "dev" because he can pack a few apps and scripts into a zip file (one guy in irc called them "Winzip ROMs). It's like there's a legion of Enyo's over there.
There are also more kernels in Rootzwiki than a Pop Secret factory - same problem as the one with ROMs. If you don't know the "dev", you really are taking your phone's life in your hands flashing them.
Has anyone seen John Connor?
