On iOS, what's the benefit of OpenSSL over using CFStream, CFNetwork etc. for secure sockets?

One obvious benefit seems to be the low level access you g开发者_StackOverflow社区ain from using OpenSSL. But, I'd like to know if there's anything (important) that you can do with OpenSSL and not otherwise.

Secure Transport (the SSL/TLS implementation available on Mac OS X) is not available on iOS as of version 4.2.1. Third-party developers have to use the URL Loading System or CFNetwork (the latter optionally together with NSStream).

I checked this again and the only benefit of OpenSSL seems to be it's range of cipher suites supported. Also, OpenSSL gives you a much granular control of the entire process, but this may be superfluous for most applications.
