We saw a leak of the phone a couple of weeks back, but now the LG Optimus Sol has got an official release in the UK and with it comes the official confirmation of just what it offers - and why it is called 'Sol'.When it leaked, we were indeed confused about the name – why Sol on a black phone? Well, that sunshine name is down to the 3.8-inch Ultra AMOLED display, which has a two-fold advanced reflection rate compared to standard AMOLED displays. The result is improved performance in (you guessed it) bright sunlight. Hence the name. Shame it wasn't launched over here at the start of summer really, although it should serve you well if you fancy some winter sun.Not just a buddy on your package holiday, the Optimus Sol, also going by the less interesting name of the LG E730, is a pretty decent Android smartphone in its own right. The phone runs on the Android 2.3 Gingerbread OS and packs a five-megapixel camera with auto-focus, a 1GHz processor, 512MB RAM, 150MB of basic storage (although a 2GB microSD card is thrown in), Flash 10.1 support and DLNA to hook up to your TV. Power consumption should be good too. If you opt for the Dark UI, the Optimus Sol uses less white light and extends battery life - a 20-30% saving in theory.The LG Optimus Sol is loosely planned for a September launch in Europe in a choice of black, titan (presumably silver) and white. If we hear about any network confirmations, we'll let you know.
