So some of you are no doubt patiently waiting for your device to get Ice Cream Sandwich (Android 4.0). Those of you that don't want to wait are looking to custom ICS ROMs which will be out before any official firmware update. In fact the official updates will be around in early 2012 at the earliest. Some devices will have a longer wait. If you don't want to wait and your device is rooted, head on over to XDA Developers. A member of XDA has started a thread that details a list of devices that have a custom ICS ROM and what status they're at. You'll be pointed in the right direction for your device. 

What are you waiting for? Head over to XDA now to see whether your device has a working ICS port.
