One of the noticeable tweaks that we see in the leaked ROM is a Quick Settings tab found in the pull-down notification bar. It lets you easily turn the smartphone's Wi-Fi, GPS, Bluetooth, cellular network, and hotspot feature on and off eliminating the need for having a dedicated widget for that. Other than that, the user interface experience looks and feels pretty much the same, as you can see in the video below.
User feedback regarding the leaked Gingerbread build has been quite mixed with some people reporting Wi-Fi issues and stability problems. On the other hand, others seem to be having no troubles at all and are saying that their myTouch 4Gs are running smoothly. If you feel like giving the ROM a shot, please, be careful and back up your data first. Feel free to share the experience with us in the comments below!
You can download the leaked ROM from the 911HTC blog.
