I must disagree; imho all of that is FUD. Whether or not a device supports
Flash is irrelevant in this case - if the iPhone is on AT&T, and has the
standard iPhone AT&T data connection, I would stake money on it being that
nonstandard ports are restricted to HTTP and a handful of others by AT&T to
manage their network usage, and VNC traffic ports fall outside of the scope
of allowed ports.

The iPhone still fails, but for more and different reasons ;) </flame>

I've encountered this exact same problem (but with FTP and email traffic as
opposed to VNC) on an old mobile provider in the UK - I was using my
handset's 3G connection as a tethered mobile broadband connection. I had to
upgrade my package to unblock the required ports, no two ways about it.
