I'm wondering if anyone has a list of linking CFNetwork version numbers to the version of iOS? I've found the list for OSX CFNetwork versions but it's quite old.
CFNetwork is a low-level, high-performance framework that gives you the ability to have detailed control over the protocol stack. It is an extension to BSD sockets, the standard socket abstraction API that provides objects to simplify tasks such as communicating with FTP and HTTP servers or resolving DNS hosts.
I made this list from some of the devices I had around at the time. It's not complete but hopefully it is helpful for someone else.
