Ice Cream Sandwich Running on a Nexus One (Video)
Once Google releases an SDK for their latest version of Android, it’s never long before someone picks it up and starts porting it to other devices.
Like most SDK ports, it’s not perfect: Wi-Fi doesn’t work, video decoding doesn’t work, audio has hiccups, and it’s a bit unstable. In short, you’re not going to use this as your daily driver.
Even still, ICS is running fairly well (albeit buggy) on the somewhat dated hardware of the Nexus One.
