So what you do on Account A (yours) is you run 11/12 ICC, but leave before you kill Lich King. Then you go in Account B (friends), run into ICC, and accept the 11/12 lockout. Now he's saved to 11/12. You go on your alt on Account A (yours) and you kill LK. Your other toon is still saved to 11/12, so we won't be killing LK with him. We're going to go back on him, click O (by default), click on Raid Info, click on Icecrown Citadel, and click Extend Lockout. This will extend your lockout to next week, and then you can repeat the process.
I used to use two accounts and have a level 80 extend my lockout every week, and just transfer the lockout to my main and my other account, which both had a 90.
