Just go to your DM and go to Add/Remove programs and then check those apps. And hit finish and they will be installed on your phone. Then if you have pin contacts that are missing just restore from a previous Back up.
I tried doing that...but they do not show in the application list.
Please correct me is I am wrong....after connecting the phone with the USB, i start the desktop manager and then application loader. This application would allow me to add and remove softwares/applications on my device.
But then the list is empty. It shows me only Facebook and Windows Messanger which i installed today.
