iPad cellular data trouble? Read on.
Just a brief note today - I had problems with the iPad's cellular data (3G) on o2. I couldn't find a way to set up an account to start a 3G service. But I found the solution and it was an easy one: plug your iPad into iTunes and update. I'd already plugged it in the first time I used it without any update so it may be new. You'll get an update to your cellular data settings which will give you the option of setting up an account.
