Found this on the BT site by accident http://www.productsandservices.bt.co...?topicId=35287 and think it's a good idea and quite generous of BT (for once.........) not sure if it works though because my handset refuses to download it!

Would like to get this app working on my iPhone, have got to the final step 3 of 3 & have tried numerous times to get the PIN sent to my phone and... nothing, rang BT and they know nothing of the app
