I've downloaded binaries for iOS and launched it and after 2 hours it was still syncing, is that ok?
It's usual situation. Now it require much more time for synchronization (about 4-6 hours)
Did you use command 'save' or 'exit' before you closed the window?
I have typed 'save' in command line. I've already read that if you don't save it the process will start from the beginning.
