@sylfan:
I don't think there is a way to test the theme without a device. However, you should be just ok by filling the image. Once you are done with it, it should *just work*.

@rcadden:
Current version does not work on latest firmware of N800. It will work on the previous two though (and all firmwares of 770). I'll make the themes to work on n800s latest firmware as well this weekend. It shouldn't be that big a problem.
