The AssistiveTouch touch is a neat little trick! Glad it worked for you. I still haven't signed up for the 4g yet, I have to go to the Sprint store to add it to my account, they won't give me their 2gb for $14.99 over the phone
I am currently using the 3G off of my iPhone.
Do you guys have a good recommendation for an OBD reader for the iPad? And an App to go with it? I ordered the anti glare screen so it should be here tomorrow.
