The "Dream Team" that brought you the iOS 5.0.1 Jailbreak is presenting at HITBSecConf in Amsterdam on May 21 - 25th. The team includes p0sixninja, MuscleNerd and pod2g.
Here's more info on the conference from the hitb website:
The main aim of our conferences has always been to enable the dissemination, discussion and sharing of deep knowledge network security information. Our main focus is on new and groundbreaking attack and defense methods that have not been seen or discussed in public before. HITBSecConf events bring together a unique mix of security professionals, researchers, law enforcement and members of the hacker underground under one roof and our flagship event in Malaysia sees over 1000 attendees.
The event runs over a 4 day period with 2 days of intensive hands on training sessions followed by a two-day conference with either three or four concurrent tracks inclusive of a hands on lab session (HITB Labs) and 15 minute lightning talks (HITB SIGINT). The HITB Labs caters for only 50-100 attendees and these sessions are intensive, hands-on presentations that require audience interaction. The HITB SIGINT (Signal Intelligence/Interrupt) sessions on the other hand, are designed to provide a quick 15 minute overview for material and research that's 'up and coming' - stuff that isn't quite ready for the mainstream tracks of the conference but deserve a mention nonetheless.
