I am having a problem on my iphone 5. The pictures i take are not being uploaded to the photostream but the pictures are downloaded fine. where as my wife's iphone 5 is uploading and downloading the pictures to photostream. We are connected to same wifi network. I have cisco e2000 router. I have even reset photostream from icloud. I have switched off and on the photostream on my iphone 5 but no use. What can be done? Thanks
