Hey guys, I've recently got the message that my phone is full and I'm trying to save space but by keeping my most important things on my iPhone (16GB). I have tons of photos but they're on a Shared Photo Stream and I'm wondering if those photos take up local storage on the device if they're not downloaded on the phone. Maybe I can upload them to a photo sharing site like Flikr and save myself some space. Any other tips? Much appreciated.
