You guys are absolutely correct in your assessment. If you have "combined" selected, passbook will not work on the lock screen with lockinfo. If you choose notification plus widgets, passbook will work correctly. Personally, I cannot stand using notifications plus widgets. From what you guys say, the developer is always ready to make changes and hopefully he will address this in the next release. Lockinfo is still the one reason that would make me jailbreak my iPhone. To me, it is by far the best hack above all else.
