Go to your photo stream on your device, select the arrow in the upper right corner then select all of the photos you want to delete. Afterwards, select 'delete' at the bottom right corner of the screen.
Hmmmm. I'm still having a problem tryna upload. Does N E 1 know if the update feature has been changed? I have been able 2 upload before. Now I receive a box with a list of file types, "choose file" is grayed out. I select "jpeg" from the list and nothing happens.
