Man I've no idea why this is so difficult, the fix is really easy, all GREE need to do is issue the game 4.4 version of the game without any of the DRM crap and the guys will be up and running. Applying the fix works it's proven, just it will only let the owner of the iTunes account it was downlaoded with to use it.
If you're out of the game for weeks you might as well just give up, lets face it how many factions will let you camp for weeks and you know GREE will never compensate you accordingly. How are you going to get back the 1 billion 1/2 billion of stats you will have lost, or even the 20 billion on cash you haven't collected.
It's even worse for me, I'm the FL of an active faction, can't boot anyone can't promote, we're in Limbo....
