Actually, Sony has brought him to court for his PlayStation 3 jailbreak, but not all companies are frowning down on his efforts - one such example is Brandon Watson, WP7 director, who has challenged him to root Microsoft's mobile platform.
To show that he stands by his principles, geohot has publicly announced that he will be "first in line" to get the Sony Ericsson Xperia PLAY and root it:
"In fact, I want the opposite reputation set, that the more a company tries to abuse the legal system, the harder we rally back. I will be the first person in line on the launch date of the Xperia Play, and itching to get my hands on the Next GEOHOT Project."
He is also pleading for popular support in his court battle against Sony. Hit the source link to read his rant against the Japanese manufacturer.
