iPhone OS 2.2 was Apple's first implementation of emoji support. This was created using private use area codes, and software-limited to iPhone users in Japan for compatibility with the Softbank emoji set. Emoji support required iPhone OS 2.2 and a SoftBank SIM card.

These were not cross-platform compatible, and have been included here for image reference. Codepoints have been updated to match the current release of the Unicode Standard.
