Well, a month apart spaced announcements doesn't mean that much. It's not like Apple copied the whole phone from LG after LG announced it, as Google and Samsung did. Android changed from a RIM copy (then the market leader) to an iPhoneOS (the new inovation leader) copy. It might be that it was the other way around, LG learnt about it from some Apple leak, but since LG's phone was an order of magnitude less sophisticated, it was announced before.
Once again, dont post without research. Google did NOT change the design of Android to look like iOS after it was announced, the stock Android look has been around since at least 2006, when it was pre-release. Go back a page and read up!
