able to run unsigned app on jailbroken iOS

I'm developing an app for jailbroken iOS devices using Xcode 4.3 (altered by JailCoder), testing on an iPod Touch 4G, currently running iOS 5.1.1, previously 5.0.1. I noticed recently I'm able to run my app on my iPod without using either ldid or a self-signing certificate with codesign to bypass code-signing requirements (as described on http://www.saurik.com/id/8). I don't have either the security.mac.proc_enforce or security.mac.vnode_enforce security checks disabled.

So why would I be able to run unsigned code on my iPod? This didn't seem to change when I upgraded from 5.0.1 to 5.1.1. My beta testers are unable to run my app on their 5.1.1 systems when not signed with a self-signing certificate. What could be different on my system? Could it be differing methods we used to jailbreak our devices?

The iOS 5.1.1 jailbreak didn't patch the code signing need to run executables. AFAIK no one apparently cared enough to do so, which means many discomfort for those who build on iOS some software as ./configure scripts obviously doesn't work. If an executable is not codesigned (or fake-codesigned), it will receive a SIGKILL.

To run unsigned code on an iDevice, it needs to be jailbroken. To easily install your custom app and debug it from Xcode (or give it to somebody else) the easiest way is to package an IPA and sync it via iTunes. However, it requires AppSync (mainly used for piracy, sadly).
