I’ve been running jailbroken on my 3GS for some time, but hadn’t made the effort to get the MyWi application working. Got it working last night, after downloading MyWi through Cydia. Magic! Not only is my WiFi only iPad just as good as any 3G capable one, but I can share my WiFi connection with all iPads and laptops in use on family roadtrips.
