You need to turn photo stream on. Go to settings on each device and under iCloud turn it on, since you already have a .me address you are using. Remember photo stream once on is only for new photos that are taken after it is activated. The syncing only takes place on wifi. From the book iCloud:
tap Settings > Photos (or Settings > iCloud > Photo Stream) and make sure Photo Stream is set to On. That’s it—no further configuration is required or possible. Having done that:
•From now on, photos you take on your iOS device (or that you add to your Camera Roll in some other way, such as by taking screenshots) are uploaded to your Photo Stream automatically.
•Your iOS device will automatically download photos added to your Photo Stream by your Mac, your PC, or another iOS device you own.
