CyanogenMod is undoubtedly the most popular custom ROM offering for many Android phones and tablets and its latest iteration, CM9, is set to bring some Ice Cream Sandwich love to Android fans (way ahead of official manufacturer or carrier updates).
However, the team is experiencing some problems with closed-sourced device drivers; until those are available don’t expect to see everything working as it should (or a port for that matter). Devices like the Samsung Galaxy Nexus, Nexus S, Galaxy Tab 10.1, HP TouchPad and Motorola Xoom are on the official support list; if you have one of these you’re on the safe side and you should expect a release soon. Samsung Exynos-powered devices as well as those rocking Qualcomm MSM8660 and 7×30 chipsets will get support in the near future.
However, if you have an older device like the Nexus One, HTC EVO or any powered by the QSD8x50 chip, you need to wait a little bit more and don’t give up hope. Check out the source link to find out more.
