WiFi Typing - WiFi Input!
You can enter text to your iPhone / iPad by using a desktop computer via WiFi, without need for any configuration or additional software, and just your WiFi and web browser will be enough.
You can then easily use this text in your iPhone / iPad, to send text messages, e-mails, copy / paste, or share to other applications, etc.
You can use the IME you are familiar with from your desktop computer for easy typing.
