didn't hackulous develop Appsync? That's the only simple method I knew of for transferring pirated apps from iTunes to the iDevice. Which is the main way the non technical users did it. Now that they've called it quits piracy will probably be drastically slowed down until there are new well known alternatives.

I could be totally wrong though, I don't own any iDevices, just basing my knowledge off helping people jailbreak their phones and pods over the past many years (except this last year of course..)
