...16gb iPhone and it says 13gb.? So I bought an iPhone today 16gb version. When I opened everything, it looked perfect. Till I checked the settings. It said I have 13.1GB available. Where is my missing 3 gigs? I checked my total usage and it only said there was 490MB used. And that the whole phone's capacity was 13.6GB. Is it the software that's causing this? That's what I've heard but I'm not even sure. Is the ordinary iPhone software and the apps that comes with apples cause this missing memory to be used? Will jailbreaking also help? Maybe if I get a new jailbroken software, it won't be as much as the one where I lost 3 gigs. I really don't know, but help me anyone please? I need suggestions as fast as possible. Thank you.
