So think about it. You're sitting at your hotel just waking up because you know your moto doesn't start until later in the morning. So you roll over, grab your phone and log on to see what's going on at the track right from your PHONE.
Oh, FYI, Iphones are currently not supported. Sorry all you Apple lovers but at the moment it just ain't gonna work. But if you have a black berry, blue berry, black jack, treo, etc... You should be able to access the live content. Keep in mind of course that depending on your cellphone speed you may get the dreaded buffer monster.
