Yes, you read right - CyanogenMod 7 for the Thunderbolt. We're super excited, too, because we can finally get our Thunderbolt Gingerbread on! But, please be careful, this is a pre-Alpha release (that means the release before the release before the beta), so be careful. Here's what does not work:
-USB Tethering does not work.
-Phone Testing menu does not display correct radio options. If you play with it, you will have to relfash a Stock based rom to 4G back.
-Possible Data/Voice bugs and issues.
-Possible Mic issues on phone calls (try a reboot)
This is basically saying your Thunderbolt might not work very well as a phone. So please, download at your own risk!
