its curious, there are multilanguage kitchen for gsm but there arent for cdma

[chborge]

I`ve seen in xda-developers multi language kitchens WWE but there arent for cdma devices like vogue or titan.
What should be done to develop a kitchen like that for kayser, elf, elfin, etc..., or what tools can be used to achieve this?
You can find them at xda-developers and in www.htcspain.com but they are only for gsm devices, whats the difference?
A I understand wm 6.1 is the os, and its the same windows mobile in all devices but drivers changes, if the changes are done in windows why cannot be done in windows mobile 6.1 for cdma devices?.
I would like to understand this
