Protocol Decode has been submitted to the app store for approval. It will easily run on both the IPhone and IPod. First release just has the IPv4 header but I’m already working on a bunch of other protocols including IPv6.

I am very excited about this application as it was the first thing I tried to find in the app store when I got my Touch. Just touch the field you are interested in and you will navigate to a detailed view. From there you can choose to see sample filters for tcpdump, Windump, Wireshark and tshark. Everything an inspiring packet decoder needs for a reference.
