この WordPress プラグインを使うと、デバイス（スマートフォン、タブレットPC、携帯電話、ゲームやカスタム）用の個別テーマを設定することができます。
This WordPress plugin allows you to set a separate theme for device (Smart Phone, Tablet PC, Mobile Phone, Game and custom). This plugin detects if your site is being viewed by UserAgent, and switches to selected theme. The Custom Switcher can add every device.
Small patches and bug reports can be submitted a issue tracker in Github. Forking on Github is another good way. You can send a pull request.
Translating a plugin takes a lot of time, effort, and patience. I really appreciate the hard work from these contributors.
If you have created or updated your own language pack, you can send gettext PO and MO files to author. I can bundle it into Multi Device Switcher.
