1.1.4。

Firmware 1.1.4 Support Coming Soon! DO NOT UPGRADE NOW.
February 26, 2008 | Posted by Ben, co-developer

As I'm sure you already know, Apple has released firmware versions 1.1.4. It appears that most of the process we currently use no longer works properly. We will have a release in 2 to 3 days that is compatible with 1.1.4 for iPhone and iPod Touch. In the mean time, do not upgrade your device.

Thanks!

機能の追加とかはなさそうなので、しばらく1.1.3のままでもいいかな
