Out of space and wouldn't start up
Hi,
My phone is out of storage and it doesn't allow me to delete my photos and videos, so i tried to delete some apps, the storage space doesn't seems to change even if i deleted 4 apps. I then tried to off it (thinking to restart) but now it is stuck at the black apple and white screen. I tried to connect to iTunes but it would not connect.
Please help. I need to keep my data.
Thanks
