myApps HandyApp - Presence sync with GSM Calls
Hi,
lot of customers are asking to be busy or have a presence state if in active call at the mobile-Phone.
I think this should not be a big thing, the smartphoneapp could read the actual call state and set a presence in myApps or set the user to busy.
With this, it is a really good solution für mobile workers 
Thanks
