Giggesh, thanks for the thread reply
Could this be accomplished by quering some other part of the system?
What i'm think is if i could access some API to get all users and their devices i could match that with the cellphone want to update, log in with the matched user and then set presence. I'm not very familiar with the presence server other then the developer guides i have read, and i don't see any way of getting such a userlist there.
Do you know if this is something which would work, or if there is even a way of getting such user info ?
