Two new Android projects finally released:
Android PCAP Capture, which uses a userspace RTL8187 driver to do rfmon without requiring a custom rom or root. Makes standard pcap files!
Of course once you have packets, how do you do anything useful with them on Android? Answer: Upload them to http://www.cloudshark.org and get Wireshark in your browser. CloudShark Uploader acts as a "Send file..." shim in Android, so any file manager (or Android PCAP Capture, natch) can send directly to the public CloudShark site or to a private CloudShark appliance.
Finally, made a G+ community to discuss wireless hacking and related. Can't seem to link to the community directly, so here's a public post advertising it w/ a way to join:
