Winterboard Keyboard Themes On iPhone OS 3.1.2

Hi Guys,

I have a jailbroken iphone 3g OS version 3.1.2 and when i install a keyboard theme in winterboard it doesnt work. I know this is an issue with the OS version and winterboard having compatability issues but there is a way around this by installing the iAcces OS3 app through cydia but when i add the repo this isnt there.

Does anyone know any other ways around this winterboard problem either with using a different theme app or anything else?

Thanks for the help
