We are very excited to finally be in possession of our Blue Model S that arrived this afternoon! We are very pleased so far. I am hopeful that some of you can help me with two questions:I have the iphone app installed but can not get past the log in screen. What steps do I need to follow to make that work and communicate with the car. Can the Model S connect via wifi yet or is cell the only option? If so, how do I connect? Thank you for any expertise you can share.
