Hi, I'm trying desperately to find room on my 16GB phone. Right now my largest user is Messages at 1.03GB (second largest is Instagram at 426.MB). So in messages settings, I can change how long I keep messages. I'm just trying to figure out if that affects the actual message or simply what's on my phone. I don't want to lose my messages - I want them to stay on my comptuer, I want to have them again when I get a larger capacity iPhone, etc but I don't necessarily need them on my phone right now.
