remember the 1 to 2 months timeframe e3 said they will release a solution to play all games.
well its just about two months since then.
red power = e3 or at least affiliated with them. both are from shenzen.
My take on the 3.55 only thing is that they may have managed to fully decrypt the 4.21 firmware, apply whatever patches are required for peek/poke, but can't re-sign as 4.21 as the private keys thus far from what I have gathered are unobtainable, so it can only be re-signed with the current 3.55 keys. All speculation of course.
