This makes me think that chunked upload from stream via NSURLConnection has been broken in iPhone OS 3.x. Unfortunately, in real life I can't upload my file by using setHTTPBody instead of setHTTPBodyStream because it's too big to store in memory.
That sounds plausible :( Is there a way you can capture the HTTP traffic to see exactly what's going on? Ordinarily I use the tcpflow utility for this, but it's not possible to install that on an iPhone. I think tcpdump can be used from a Mac/PC to capture packets from other devices on the LAN.
In any case, you should repost your questions on the macnetworkprog mailing list — this looks like a CFNetwork problem, and some of the engineers who work on that read that list.

Have you tried memory-mapping? Use [NSData dataWithContentsOfMappedFile:].
