Capcom announced that the update for the iOS version of Monster Hunter Freedom Unite was delayed but is still happening.
As spotted by Shaun Musgrave at Touch Arcade, the Japanese website said that the update will be released sometime in Spring but there have been some more issues they ran into with iOS 9.3. They will be announcing a date for the patch soon.
I hope they manage releasing the patch soon because Apple is set to unveil iOS 10 or the next major release for iOS this month with a release in Fall. Monster Hunter Freedom Unite is the PSP game that was ported and played great on iOS devices and even had online support.
Thanks, Touch Arcade.
