While most applications are meant for only the user, this should mark a change in the way they can be utilized. Tokyo based Genkii has created an app that lets iPhone users connect with others. Sparkle is claimed to be the first virtual world that links your phone to Second Life and OpenSim grids. Send teleport requests and IMs or chat with others. Sparkle is available for $4.99 now but plans include a 3D version to come with personal space, social networking, virtual games and goods, and more.
