Virtual Worlds On The iPhone?

We're not there yet ... but it's coming. Currently with an iPhone app called "Sparkle" I can log on to Second Life and connect with my friends and business associates who are in world. I can IM, chat, and transfer lindens. I can even send a TP request. Also, when I log on via my iPhone, I show up as being in world even though I may be far out at sea and far away from my computer. Of course, there is no visual presence, but hold your breath, that won't be long in coming, I predict.
