If you have been visiting geohot’s blog or any other page of him, you should be aware that Sony now has you IP address for the purpose to sue you.
As we have seen in the past, Sony doesn’t need a good reason to sue, a whim is enough.
So if you live in the US, you should maybe think what this means for you. For the rest of us, make sure you can enjoy your next trip to the states (instead of spending it in, say, a prison because you violated some law that you didn’t know about – ignorance is no excuse).
