put it to you easy
360 with Modified firmware playing originals online= safe
360 with Modified firmware playing backups offline= safe
360 with Modified firmware playing backups online= possible ban
So like I said it doesn't make sense having 2 drives although there people trying to figure out how to make a dual firmware but its unknown how far along that is at the time
actually, modified firmware playing orginals online = possible ban.
with iextreme 1.3 or earlier it's possible to get a rotation of 359 + 1 = 360 and get banned with an orginal disk with modified firmware. there have been reports of people getting banned with modified firmware, yet only playing orginals online.
it seems it won't happen with iextreme 1.4, but who knows maybe something else can.
so to be 100% safe online. orginal firmware + orginal disk.
online = signed into xbox live, not necessarily playing on xbox live
offline = not signed into xbox live, ethernet cable/wireless unplugged/not connected.
