There are at least 10 different virtual lighter applications available for the iphone, most of them free. However users are paying 99 cents and downloading Smule's Sonic lighter like mad. The thing that sets Sonic lighter apart from other virtual lighters is that it has built in social and viral, location based features " and they also give this ridiculous but effective incentive to use the app all the time." (TechCrunch) When you have your virtual lighter on, it will blaze on a virtual earth, so the more people with it on the more that location will glow. Kind of like a global rock concert.
