LG officially opened the doors to its online applications store on Thursday. The app store offers social networking, navigation, VoIP, and instant messaging applications for both feature phones and Windows OS phones. LG will expand its offerings to include an estimated 4,000 applications — including those for Android-powered smartphones — by the end of the year. Currently in beta, the app store launched with high profile titles like Spore, Worms 2010, Assassin’s Creed, and The Sims 3. It also includes an incentive program that awards you points for logging in and leaving reviews. The more points you earn, the more applications that are available for you to download. Available in 22 markets at launch, the app store will soon be available in 33 countries including the UK, Germany, France, Italy, and Spain.
