Hello Derek,
Thank you for your email. We only offer the latest version (3.0.5) for download. We don't offer old builds of iAuditor for download. Our app was required by Apple to update to be compliant with iOS 7.0, which version 2.3.8 was not.
We strongly recommend that users update to newer versions of the app as we have offered several bug fixes and improvements into newer versions of iAuditor.
If I can be of further assistance, please let me know.
Sincerely,
Haydee
