This was a very interesting article, thanks for sharing. Although it looks like he updated it to say that it does in fact use more power, but I can't imagine anyone not using data on this particular phone.
Well, the the update says that the Iphone uses more power while in a call and the 3G is on. So you would only save power if switching to 2G before making or receiving calls on the Iphone.
I suspect even this limited case is Iphone specific. The Iphone routes calls through 3G so that you can surf the web while talking. If you'll notice on the Optimus V, the 3G is disabled while making phone calls.
As it states in the article, if you are using 2G for regular data use on the Optimus V, the advantage of lower battery draw will be completely eliminated by the slower download speeds which will require you to leave data transfers running longer. And when in the idle state, 3G and 2G both draw the same amount of power. So really, in no situation is the 2G better than 3G for battery usage.
I think where people are seeing the benefit to switching to 2G on the Optimus V is in disabling and re-enabling their wireless radio in the process. This has the side effect of fixing the 50% standby issue. I bet if they then switched back again to 3G, they would get even better battery life.
At least that is my opinion
