The link farther up in this thread doesn't work because it's malformed. This link for current customers will work: http://www.aol.com/newaol

BTW, if you are a current customer with your own broadband access and you just want to switch to the free plan, you don't need to call them. You can go to AOL keyword: change plan

Edited to add: WSJ article says they may go back to forcing you to call them:
"To handle the high number of calls, AOL implemented an online switching option Thursday. By going to keyword "Change Plan," broadband members could switch to the free version in a few clicks. But the company cautioned that the option may be shut off now that call volumes have subsided, and that the toll-free number is the best way to change."
