Sorry... without an iPad myself, I am dry on suggestions. Drop the $9.99 on MyWi I guess is the last resort. I believe this IS working for folks.
I'll go pick one up tomorrow and see what I can do for you. Now I have a valid excuse to give my wife for spending $500 --- "But honey ! Ipoddin on macrumors is depending on me." HEHEHEHEHEHEHEHE
I'll back ya up on that! Mywi works flawlessly. Very fast too.
