根據Cult of Mac在iOS 4.3 beta中發現的資訊，除了早先已經被發現的PhotoBooth之外，還包含、「Sports Trainer app」、「QuickLook」以及「Wireless Syncing」等。其中「Wireless Syncing」可能為許多人所期待的無線同步功能。
不過這些功能也許不會全部出現在iOS 4.3正式版，諸如「Wireless Symcing」等較重要的新功能，比較可能在iOS 5時才會配合新硬體推出。

感謝網友提醒，目前9to5Mac的Mark Gurman已提出指正，除了PhotoBooth之外，QuickLook是在email裡打開附加檔案的功能，Sports Trainer是早已在Nike+裡的功能，而Wireless Syncing可能是MobileMe 同步的一部份。
大哥, 睇清楚先 post la, 原文一早話左唔係呢回事, 遲成日仲 post 錯既舊聞
回覆刪除"UPDATE: Mark Gurman from 9to5Mac is skeptical about this information. PhotoBooth is right, he says, but has been known for weeks. QuickLook is for opening attachments in email; the Sports Trainer frameworks have been in iOS forever, and likely refer to Nike+; and the Wireless Syncing frameworks are likely part of regular MobileMe syncing."
