Since the fact that my iPad don't have 3G, maybe I will get on of those myself.
The iPad.s were connect via wireless the connectors are just for power only Airport express is an easy answer it just works.
If you don't mind me asking, What type of phone do you have and who is the carrier?
Does it or do they support mobile tethering?
I know you mentioned that you don't have a iPhone. If you like the Ipad than you would prob. Love the IP4. Definitely the best device I've ever owned.( Coming fro a previous windows mobile & Blackberry user)
Anyways, I tether 3G right from my iPhone, a flip of a switch and I'm all set, No wires needed. Don't even need to take the phone out of my pocket.
Depending on your phone/carrier this may be a option for you.
Crockett ruled lol.
