Still rocking the HTC G1, the world's first Android phone? Didn't think so, but if you have one laying around somewhere, you may want to grab that thing and knock the dust off of it. Why, you ask? Because there's a "working" (I use that term loosely here) port of ICS ready to flash.
As you may imagine, it is incredibly slow and nearly unusable, but c'mon - you have to admit that it's pretty cool.
