I’m just waiting delivery of my New Apple TV (Latest Model - Launched Mar 2012) and I purchased aTVFlash-black from you, do I need then to wait for an update to be able to use the Apple tv to its full, and to upload the software, do I simply plug the Apple tv into my laptop (mac). sorrry if I seem a bit dim

It is not possible currently to use ATV Flash Black on that model (also,known as ATV3). ATV Flash Black can only be installed on jailbroken systems, and currently no jailbreak is available for the ATV3l. There is also no current ETA for a jailbreak becoming available for the ATV3 although there have been plenty of rumours which have so far been found to have no basis in fact.

You can also contact Firecore for a refund on the purchase.
