Really wanna go back and replay this but it doesn't seem to be availible anymore. I can find a link to it online but it brings me no where. Just sayin
Rockstar was apparently looking into an update to fix iOS 7 issues causing the intro to prevent you from starting a new game, before they took the game off the app store. Only time will tell if they actually update the game though.
I think they're working on it, like said they will address the issues. Hopefully they'll re-launch it with universal support. Not paying twice for a iPad copy. I paid for the iPhone one already!
I'm assuming since you said "replay" that you already bought it. If that's the case, you can still download it from your purchase history. They just hid it from new customers.
Wow, I'm glad I found this thread. I was going nuts trying to figure out WHY chinatown wars wasn't working anymore. I really hope they address this issue. And adding iphone 5 support might be nice as well.
