Where did polar bears live before the Arctic Ocean became frozen over every winter?

This actually comprises several questions: 1/ Does the survival of polar bears depend on the Arctic Ocean being frozen over every winter?; if "yes": 2/ For how long has the Arctic Ocean been regularly frozen over every year? and 3/ Were there any polar bears before this time and, if so, where and how did they live?
