Do you remember when Android 4.0 Ice Cream Sandwich first came out? Ports started springing up everywhere because everyone wanted a taste of the update. Android 4.1 Jelly Bean is receiving the same amount of love from Android users and developers. The T-Mobile myTouch 4G is the latest phone to build a CyanogenMod 10 port, which means that users can enjoy all the new features such as smooth as butter performance, an improved keyboard, and a whole lot more. You have XDA Developers member 0.0 to thank for that.
Because this CyanogenMod 10 port is still under development, there are a number of things that aren't working quite yet. Backlights don't work with auto-brightness set, so you may want to turn off auto-brightness. The camera works but not perfectly. Setting the camera to 5 MP leaves a green line on the side, reminiscent of how the first working Ice Cream Sandwich camera, and the front-facing camera does not work. Video recording also does not work but if you're content with only using the rear camera for taking pictures, such as for Instagram, then this shouldn't be too much of an inconvenience. Keep your chin up because the developer is working on fixing these.
