I'm not quite sure about whether "Available in Mac OS X version 10.1 and later" means that it's not available in iPhone OS. But, I assume everything that exists on iPhone OS reference library, exists on iPhone OS, because that's also the case with NSURLConnection, which obviously exists on iPhone

CoreFoundation exists on the iPhone. And you can look at cocoadev.org for a decent HTTP Post example there or look on Google code for a class that does Flickr uploads through HTTP Post and that works on the iPhone. HTTP Post is not hard, but it does expect a very specific way of doing it.

In all honesty the easiest way is to do it in C. Add a 4 byte variable to the top of your packet header.. When building the packet set it to 0.. That solves your problem of getting data into the packet. But if you want to add something to the beginning, using NSMutableData, you have to firs

Hi, Ian, From a cursory glance, the issue would likely be that you're using %@ in your NSLog statements, rather than %i or %d. %@ is used for NSObjects, generally NSStrings. You'll want to replace that with %i or %d since your -numberOfSides and other methods are returning int values.
