Using Two Different Languages on iPhone:
Best you can do, as of this reply, is add a new keyboard. This allows you to type in both languages without needing to switch keyboards. So, if that meets your goal, I'd say your all set.
- Go to: Settings
- Tap: General
- Tap: Keyboard
- Tap: Keyboards
- Tap: "Add New Keyboard"
- Select: [the language[s] you want manually]
