Today i downloaded the upgrade for igun and for some reason it's still stuck on 0% Then I thought maybe it's the game so i downloaded a couple of others all on a grey box with nothing downloaded. My iphone is not jailbroken or modified it is not full I still probably have about 15gigs left (16g iphone 15 games got it last week) . I was watching a youtube vid that kept on freezing while the first 1 was dowloading does that do anything. When I look at these games in the app store it says installed when in reality they're all grey boxes with an empty download bar. If you're connected to a router can u exceed ur amount of gig in a month while using iphone is that the problem. Also with one of the when i dwnloded it said this item is no longer available all of that apps i have r free. Please help i'll be very greatful.
