That article is a joke. It appears to be based entirely on this Reddit thread. In the thread, exactly three users complain complain that the update does not fix the issues for them two of them are in Australia, and one is in California.
Somehow, two Australians in a forum (full of other posts saying the update fixes their issues) having problems merits an article titled "Apple iOS 8.0.2 update backfires on Australian users." Someone ought to be fired for such shoddy journalism.
