You actually won't be able to delete the programs from your phone. You have to actually log onto the computer and then delete it from there. Maybe in the future we will have the option of deleting it from our phone.
there is I did it a couple of hours ago,you simply just click on the photo so it comes up full screen,then just press your finger down (hold it down) and it comes up with either: make this your profile picture,delete this phone ext. So I hope this will help ;) xx
