I've had my iPhone 4S & iPad with retina display for a year with no probs until recently. The other night I noticed that 90% of the pics on my photostream on my iPad were blank or they just said 'JPEG" where the pic should be. However all 1000 pics on my photostream on my phone were still there. photo stream is switched on on both devices. Tonight I have noticed that I have emails on my iPad email from as far back as last Sunday but when I access my email on my phone it says that I have no emails. Any advice or help would be much appreciated.
