Owners of the Acer Iconia A500 Tablet with a penchant for tinkering will be glad to hear that a new ClockwordMod and a new custom ROM have already been created for the device. The custom ROM is actually based off the ASUS Eee Pad Transformer, which is rather ironic. For users that want to get busy customizing their Acer Tab, hit up the XDA links below, and as always before to follow the instructions carfeully so you don't "brick" your device.
