If you're wanting something made by Apple, for jogging with, and no WiFi, I'd go with an iPod Shuffle or an iPod Nano. The Shuffle and Nano both have a clip, making it easy to clip on to clothing. The Nano also has an FM Radio whereas the Shuffle doesn't. But that being said, if you do want to go with an iPod Touch, Apple does sell different armbands for all different iPods models, here. Hope this helps you in your selection choice.
