After enabling all those keyboards, wouldn't you love to be able to select your country's region format too? Naturally on iPhone 1.1.2 you're only allowed to select those region formats that correspond to a supported language.

This patch enables all region formats on iPhone 1.1.2. This can't be done through plist modifications.

To install, simply add http://cynix.org/iphone.plist to your Installer sources and install the More Regions for 1.1.2 tweak. You'll find it in the Tweaks (1.1.2) category.
A new and improved patch has been released. See More Keyboards & Regions for 1.1.2 for more information.
