I saw a modde xbox 360 being offered on craigslist. I asked him if it was flashed withe the current iextreme firmware but he was not sure and told me that it was flashed a year ago. Can anyone speculate if an xbox modded a year ago would have the new iextreme firmware. Secondly is there a way to tell from the the xbox dashboard what its flashed with or would I have to connect the xbox to my pc ves sata cable to find out? He assured me that it plays backups. But I want to be certain that it plays current backups and not backups from games from last year. Any comments welcomed.
