How can I fix problems I'm having with the iPhone app?
Please delete the app, and then download and install it again from the App Store. If this doesn't help, please let us know which iPhone you're using as well as your operating system version and app version and whether or not your iPhone has been jailbroken (if you don't know what the latter means, then your iPhone will most probably not have been jailbroken ;-))
