В рабочем проекте проверка целостности под дебагом не проходит, но если запустить приложение в симуляторе без отладчика, то проверка проходит нормально. На девайсе тоже все ок. Как я понял вся проблема была в, цитата Вашего поста из соседнего топика, "Проблема была в новых механизмах, которые apple ввела в ios 5.1 для защиты от джейлбрейка (ASLR).", а не появится ли эта проблема с выходом iOS6?

При импортировании #import <CPROCSP/DisableIntegrity.h> возникают ошибки компиляции

Здравствуйте. Контрольная сумма считается только на сегмент кода, он не должен модифицироваться при подписывании. Можно копать ещё вот в какую сторону: обычно в проектах разные настройки для линковки приложения при ad-hoc распространении и при сборке архива. Поищите там опции про dead code stripping, strip during copy, strip linked products, strip style и тому подобные и выключите всё. Ошибки типа NTE_PROVIDER_DLL_FAIL могут быть связаны как раз с этими настройками.
