Pixie Network Monitor by 9bitlabs: Pixie Network Monitor for Android - Home Page (I am not the developer ) It is a network monitoring app similar to Wireshark, but for Android. It is $4.99 on the Android market, it requires root, and it does not work on all phones (since not all phones can have their wifi put into promiscuous mode). There is a companion app called "Pixie Probe" available on the market for free. Pixie Probe will determine whether or not your phone is compatible with Pixie. I have tested it out on my Evo (running CM6.1 RC1) and it seems to work amazingly well. Pixie allows you to view all wireless network traffic on WEP and Open wireless networks (including traffic from other devices ), but does not contain all of the features of Wireshark/Kismet. This is from the Pixie FAQ: The Pixie website gives very detailed information about the app, so I suggest you go there if you want more info. In any case, I hope other people find it useful.
