The update 3.72 coming out, it was questionable whether any action against the hack was implemented, it would seem not.

It did not take long for Team E3DIY to show the dual-boot 3.72-3.55. The downgrade 3.72 to 3.55 is also functional. The team also announced a new clip included in the pack limited 3K for the same price, for not being welded. So all the PS3 Slim and Phat NOR are compatible and requires no welding. The original deadline for Commercialization is delayed for adding this new clip in the package.
