IMessage - No SIM - Other Devices?

I have a jailbroken iPhone 4 with the SAM unlock in place, to fix iMessage and Push. I've never put a SIM card in the thing, and never plan to. After much dismay, (thinking the SAM fix wasn't working for iMessage), I found that it did work, but only for other iMessage users (I assume this because I just texted my own address and it worked).

Is there a way for me to be able to text other devices not running iMessage using this (or any) method?

Can I sell an item on eBay that is patent protected?

I'm selling an item on eBay and I've gotten 2 emails from some guy in Germany saying that I can't sell my one, used item because it is patent protected. The email says it should be removed from eBay. I don't see why this is any different than selling something like an iPhone. The item is not prohibited by eBay in anyway, and eBay has never contacted me.

Can I get someone's Wi-Fi password with their ip address?

Long story short, my Wi-Fi was shut off and I have perfect sig on my Xbox to the neighbors, but they have a password. Now somehow, my iPhone connected to it with no password or anything, and I got their ip address, subnet mask, and a bunch of other stuff. I want to know if there's a way to go DOWN the stairs (metaphor), and get their password, considering I got everything else. Thank you (btw I'm not cp savvy at all so being basic would be much appreciated)
