I just set up my photo stream to be able to download all of my photo's taken with my iPhone into Aperture. For some reason it's only going back but so far. I only have 30ish of the 230 photo's on my iPhone. I stopped photo stream and restarted, but it didn't seam to do any good.
Also, if it only does it over Wi-Fi. Does the wifi on my phone stay on when it is locked?
