Jordan Yee ponders: “I’m just putting two and two together here, so hear me out: if an iPhone 4 can only make FaceTime calls over WIFI like the iPad 2, could an iPad 2 make a FaceTime call over 3G by connecting to an iPhone 4’s Personal Hotspot feature which is WIFI?” Absolutely. This already works on Jailbroken iPhones with MyWi installed. Um, that is, so I’ve heard. (via Daring Fireball)
