I submitted the new version last Wednesday, so I expect it to be available by next Wednesday. This is my first submission after the release of iOS 5.1. Hopefully everything will go smooth.
The new version contains adjustment of the content - it introduces only one new member (vowel or consonant) at a time. (Thanks Jim for your feedback.)
previous chapter 2: 다라 - 더러 - 도로 - 두루
new chapter 2: 다더 - 라러 - 다라 - 더러 - 도로 - 두루
I hope this minor content tweak helps you in later chapters (14, 15) when it introduces composite vowels.
Also, I changed the color of page number to be blue. It was clickable from the initial version and it shows chapter selection dialog, but people didn't seem to try that since it doesn't look like a link.
