The first PSP hacks have begun to be widely circulated around the web, including one dreamed up and realized within 24 hours. Robert Balousek needed just a day to get IRC (Internet Relay Chat) working on his PSP, more info and how-to at his site PSPIRC. Other hacks include a hack to transfer TV shows recorded on TiVO to your PSP, an eBook reader, and a viewer you can use on your PSP to read comics downloaded from the internet. The hacks use the browser feature of the game Wipeout Pure, so you'll need a copy of that to try these out.
In other PSP news, Sony has announced that it sold 500,000 units in the first two days of the North American release. Not bad!
