I will be using an in-flight wifi service (Gogo Inflight) today for the first time. It looks like the service costs $9.95 for a laptop and $7.95 for a mobile device. I would like to simultaneously use a laptop, iPad and Blackberry. I know that I can get a network connection to the Blackberry via USB, but can I get an internet connection to my iPad via the USB once connected on my laptop?
