No it only comes on the GSII from Samsung mobile. I've seen it also on the Galaxy tab. Unless someone can extract it from the ROM image, maybe at xda developers I'm sure someone can do it.
PS: there are actually two widgets, the weather widget from accu weather which auto updates in increments of like 3 hrs and it adjustable to a bigger size and the clock widget. Together they look like one single
widget, but they're not.
