What I mean is that technically you can do it without jailbreak, but that would involve black magic (that is, abuse the app sandbox to create one single rwx mapping which is required for JIT hence allowed under limitation on iOS) and run the risk of being rejected by Apple. I know some security expert released a method of loading signed dynamic library from outside the application bundle (in his case, downloaded from some server) on vanilla iOS (vanilla in contrast to a jailbroken system) and from my personal experience a dynamic-linked OpenSSL worked on my test environment.
This is taking the thread off topic so I think this is it.

Apple does not allow any dynamic libraries exist in App Store packages (“Nobody but Apple can put dynamic libraries onto iOS device") so the dynamic library support is pretty much restricted to jailbreak community.
