For the purpose of arguing, let's say that you like the way Android looks, but need the functionality of a BlackBerry. You could carry two devices (and receive two hefty wireless bills as a result), or you could download an Android theme for your BlackBerry. Thanks to the good folks at EThemes, those carrying a Bold, Curve 8900, or Tour can rock out with a Sense UI theme without having to purchase the Hero.
To download to your BlackBerry, click on the links below (note: all links are OTA, meaning you'll have to access this post from your BlackBerry to click on the links).
