The process generates an impressively high-quality--and rather large--image file that rings in at 10,800 by 2470 pixels. (A test shot I did ended up as a 17.8MB file, so keep that in mind before you start emailing them to your friends.) It's worth noting, however, that this isn't a 360° panorama--it's probably more like 270°. Also, the smaller area you're trying to capture, the more curvature you'll get--so landscapes will probably look more impressive than, say, your home office. Still, it's a remarkably easy process that produces a pretty seamless image.

iOS 5 brought Twitter integration, so I suppose it's only fair that Facebook get its day in the sun. If you've used the existing Twitter integration at all, you'll find the Facebook options pretty straightforward. In pretty much any place you can Share something, you can now post it to Facebook in addition.

First, you'll need to configure it by visiting the Facebook section of Settings. You'll need to enter your username and password--or create an account if, horrors, you're one of the few who doesn't have one. Apple will provide you a lengthy list of things that you're giving access to, along with telling you to disable many of the features. You'll also be prompted to download the if you haven't already.

Once you've set up Facebook, you have some options. For one thing, you can choose which apps can access your Facebook account--by default, they include the App Store, Calendar, and Contacts, but other apps can request information as well, which it's up to you to allow or deny.
