I'm Japanese. In Japan, the main messaging app used is Line, and I use it too. Then I thought, "I want to use Line on iOS 6." I looked online, but the version of Line for iOS 6 has been discontinued and is no longer available. So, I'd like to ask for help from you who are reading this. I'm wondering if there's any way to use a jailbreak tweak, patched ipa file, or whatever to get Line to work on iOS 6.

By the way, I have a jailbroken iPhone 4s.
