I doubt you'll find any... WEP cracking is pretty much a "done deal," so no one's that interested in it anymore, and WPA cracking is pretty much undoable, and the folks who might still be trying to crack it are almost assuredly using desktops or laptops for the faster CPUs. If you do a little war driving these days, realistically you're going to see lots of unsecured networks and lots using WPA or WPA2. Very few will still use WEP.
