Second Federal Savings continues to offer a special 4.00% APY 4-month CD and a 4.20% APY 13-month CD. Minimum deposit for the 4-month CD is $2,500, and the minimum for the 13-month CD is $5,000. These rates are listed at the bank's promotion page as of 12/07/08.
It appears that a branch visit is required to open an account. Branches are located in Chicago and in Cicero, Illinois.
In my last post on this bank, a commenter described some poor customer service he experienced when he tried to open a CD at this bank. He called to confirm the special CD rate before visiting the branch. After driving an hour to reach the branch, he was told that the CD had been discontinued at 11:00am, and the branch manager refused to honor the rate even though they had quoted the rate to him earlier in the day. As listed on 12/07/08 at the Better Business Bureau website, this bank has a "unsatisfactory record with the BBB due to a failure to respond to a complaint."
The bank has some decent financial ratings for soundness: 4 stars (excellent) at BauerFinancial and 3 stars (performing) at Bankrate.com. It has been FDIC insured since 1934 (FDIC Certificate # 27986).
