I have an iPhone 4S and iPad 2, both set to share PhotoStream (I'm signed into both devices). I NEVER get a consistent update of photos on the iPad. Case in point: Went to Cincy Labor day fireworks last night. Walked down by the Ohio river to watch. Took a ton of pictures with the iPhone. Afterwards we walk back towards town (with thousands of other people, haha) and stop for a late dinner at Taco Bell. SO, 'bout an hour after the photo's were taken, we get back to the hotel room and I open the iPad up. About TWO of the photo's synced over out of all I took. By morning, another couple made it, but not nearly all of them. Details: Both devices are on wifi and both are set to share PhotoStreams and I shut down the camera and photo apps after taking pictures (because I read somewhere you needed to). The whole thing seems very inconsistent. Even when I'm sitting at home on my own wifi, not all of the photo's make it over to the PhotoStream. Sometimes they go quick, sometimes they never show up. Can I ask wtf is it with this service? I never get a decent sync out of this.
