It's kinda pointless to have a cab for themes, as it can't install them--just copy them. You might as well put your extra themes on a storage card. That's the best place for them (since you only ever use one theme at a time and when you install the theme it gets copied to the device. You can remove your storage card and your chosen theme will stay). To install themes just put them at the root of your storage card, go to settings->today and select it from the list, hit ok and voila.
