That site went up before the Touch was even available, they just wanted to have the first Touch hack site. Hopefully they will now update it with latest info.
As others have said, there are torrents for the iPhone apps, someone posted a link in another thread already.
Future updates will likely break the hacks, but hack updates will remedy that. Apple has already said they aren't going to go out of their way to disable or prevent hacking, they're basically not going to worry about it either way (meaning they obviously aren't going to support it either.)
