I have updated the Gingerbread keyboards posted here to be installable. Now, you can install along side your Android keyboard and switch back and forth. I have expanded the themes as well with more color. To install one fo the keyboards, follow the below instructions.
- Download preferred color
- Remove .zip from the filename (Ex. Rename blue-gbkb.apk.zip to blue-gbkb.apk)
- Remove any current Gingerbread keyboard
- Install like any other app
Green Gingerbread Keyboard
Blue Gingerbread Keyboard
Red Gingerbread Keyboard
