The contacts page has a filter menu, called "Groups," which doesn't use tabs. When you choose "Groups," you are shown a menu of all of your accounts, and when you choose an account, only contacts from that account are shown. The "All contacts" at the top is replaced with the account name, the "X" in the top right is replaced with a back-arrow, and clicking on the back-arrow returns to the "all contacts" page. Seems like this should also work for filtering the call history.
