well almost since launch, ME2 players on the PC have been able to edit their save games to give them money, additional skill points, or resources (the most important one, since you don't have to mine any planets whatsoever). well i stumbled across a thread on the Bioware forums that lets Xbox 360 players do the same

i tested it just now and it worked perfectly, using a USB key was the most simple solution. now i can playthrough on my main 360 character since i screwed up some of my choices the first time around without wasting so much time scanning planets. you can even put in custom eye colors and
hair styles for female shepherds that are in the game, but not available normally for you to use in the character creator. another neat thing with the Gibbed save game editor is that you can change any decision you made in ME1, so you can make a new playthrough without having to start over in ME1
some of the custom combinations that are out there are pretty sweet
