How can I type in different languages / turn on International keyboards?
The iPhone supports many different keyboard characters from around the world. To turn on one or more International keyboard(s):
1. Touch Settings -> General -> International -> Keyboards
2. Turn ON the keyboards you wish to use
3. When multiple keyboards are switched on, a globe symbol appears to the left of the space bar in the keyboard. Use this button to switch between International keyboards when typing.
4. Many keyboards have additional hidden keys. To access these characters hold down a key on the keyboard and variations of that letter will appear. For example, holding down the letter E on the English (US) keyboard brings up 8 different options.
The iPhone has built-in keyboard support for the following:English (U.S.)
Traditional Chinese (Handwriting, Pinyin, Zhuyin)
Simplified Chinese (Handwriting, Pinyin)
