There is this app "wardrive", of course it only preforms wardrive operations but it does it very nicely!
I have looked at some forums for apps for WEP-cracking, injecting and similar actions for Android, but there don't seem to exist at the moment.
People talked about booting a Debian/Slackware/Backtrack distro, and I for one would love backtrack tools like aircrack-ng etc on our devices.
But all in do time, I think it will appear when the platform is more mature. Until then, we can map with the wardrive app and use our lappies for the more serious stuff. For fun, here in Sweden these kinds of apps is not illegal :)
Not impressed with Froyo!
