As you know, it's illegal. Cracking a WEP is not impossible but sniffing it is a long, tidius process. 10 digits, can be all 1s, 1 - 0, a phone number, etc. I don't advocate illegal stuff, I suggest save up $40 bucks and get your own sexy WiFi signal with uber-strength. That way you can use it for anything witout the risk of someone logging you.
