The iPhone 4 hasn't been able to display any contribution pages (such as Special:RecentChanges, Special:Watchlist, or Special:Contributions) with high amounts of pages listed for positively ages, and that situation probably won't be improved since the iPhone 4 is stuck with iOS 7, and the problems started when that was released. It's one of the reasons I've been using my phone less and less to access Wikia.
