Have an iPhone and and another iOS device like iPad 2 or iPod touch 4 and curious how to use personal hotspot to place a FaceTime video call over 3G? We showed off the feature in our TiPb TV iPad tourist video and mentioned it as a bonus in our how to connect your iPad to iPhone personal hotspot tip, but enough of you wrote in to ask about it we figured we better feature it in a tip of its own. And we're doing just that after the break!
While you can't do a FaceTime call on an iPhone 4 or iPad 2 over 3G, for some flummoxing reason you can turn on personal hotspot on iPhone 4, connect to it on another iPhone 4, iPad 2 or iPod touch 4, and make all the FaceTime calls you like. Here are the steps and each one is a link to previous step that gives you more info.
The quality is good, better in fact than I remember it being with Jailbreak 3G enablers for whatever reason (though Jailbreak doesn't require a second device). Just remember to keep an eye on your iPhone's battery life and data cap!
Tips of the day will range from beginner-level 101 to advanced-level ninjary. If you already know this tip, keep the link handy as a quick way to help a friend. If you have a tip of your own you'd like to suggest, add them to the comments or send them in to firstname.lastname@example.org. (If it's especially awesome and previously unknown to us, we'll even give ya a reward...)
