I have been having lots of issues recently with the iPhone App - the prime one being if you try to update when you are out of range of a cell signal or wi-fi.....obviously you get a "no network connection - please turn on data roaming message" ......but infuriatingly ....once you do have a strong 3G signal and/or wi-fi signal ...it keeps saying the same thing - forcing you to switch the phone off and on again to correct it?

....another issue seems to be if you have an American Airlines flight in your itinerary...it won't let you get a BL on any of the subsequent BA bookings?
