Which contact goes into Wikitude BBM contacts?

[mss-ca]

I have a question how BBM contacts work on wikitude browser.

Assuming that the user given the permission to be visible on the wikitude system(so I can find them on my phone); When you move around with your Bold 99xx with the wikitude, the BBM contacts it shows only from users with new line of Blackberries came out recently OR it includes ALL Blackberry users with all previous generation devices as well?

Another question I have is...
Is wikitude BBM contacts are BBM App version dependent OR is it device model+app dependent?

NOTE: When I talk about BBM Contacts, I don't mean the contacts you already have on your BBM contacts list, I mean those strangers around you.
Thank you.

I THINK everyone who has the App and set themselves "visible" every time they open the app they are marked in that place, then they will show up in your radius, so if someone out of town comes to your town and launches wikitude then go back to their town they would still show up in your radius when you search contacts, like it says 'was seen here 2 days ago' etc (that was all a guess lol)
