Ahhh... ok. I see what you mean. I was wondering since I know there was a driver that was helping with getting better battery life. I was wondering if that was it.
2.0 is SDK5, yes. Actually, I think, from what I can see, they did some kind of hybrid but it is not all 2.1... so, technically, it is still 2.0.
Still working on the repack. I want to get the right way to make it easy to flash the ROM.
