While much of the world is still waiting for the first official smartphone running Android 4.0 'Ice Cream Sandwich' - the Samsung-manufactured Galaxy Nexus - to be released, hackers have ported the open-source platform to the Nexus One as a taster.
Released as the hero-phone for the Android 2.1 'Eclair' software launch, the Nexus One was Google's first attempt an an own-brand handset. Manufactured by HTC, its specifications were impressive at the time, although the Qualcomm QSD 8250 1GHz processor, 512MB of RAM and mere 4GB storage show the device's age.
Replaced by its Samsung-manufactured Nexus S successor, the Nexus One is now three smartphone generations old - but that hasn't stopped hackers porting Android 4.0 to the device anyway.
An XDA Developers forum member known as 'TexasIce' has released a video of the Nexus One running CyanogenMod 9, a third-party build of 'Ice Cream Sandwich' based on Google's publicly-released source code.
While things aren't perfect - there's no support for the device's camera or USB mass storage facilities at present - it's surprisingly smooth, with the slow processor causing little lag and the handset only beginning to struggle when some of the operating system's more advanced graphical effects kick in.
Google has already confirmed that the Nexus One won't be getting an official upgrade to Android 4.0, meaning that CyanogenMod - and similar third-party ports - represents Nexus One owners' only hope of getting their hands on the software without paying for an expensive upgrade.
The thread detailing the porting efforts is here, and TexasIce's video is reproduced below.
