I have had a trawl round the web and this forum and found nothing. My company uses a bunch of 7230's for it's chosen few (me included). Anyway, one of the chosen few has complained that since she got her BB her train ticket (london underground) has stopped being 'read' by the automatic entry gates. She has been having to get her ticket replaced once a week and the station staff are not happy.

She is blaming her blackberry as she stores it in the same bag as her ticket. Now I am sure it is a powerful device when the wireless is turned on (anyone who listens to the radio with one less than a yard or two from it will agree with me), but can it really damage the magnetic stripe on the back of a rail ticket?

any views?

My only suggestion has been to turn the wireless off when she is not using it (as we do not use them for recieving voice calls) and seeing if that makes a difference.

The magnet in the case, that puts the blackberry into sleep mode, might be causing the problem.

Can anyone confirm if blackberrys transmit constantly? I thought they would only transmit when sending / receiving emails or data...

They only transmit during recieve and send.

I have combined about 30 different types of cards and readers like her train ticket mentioned above and have never noticed a problem with any of them. Matter of fact our cardkey entry system at work, as well as my metro pass are of the type she probably uses, and I keep them on my belt right next to my blackberry. I highly doubt the magnet in the holster or the BB itself could be the culprit.

Does she have a habbit of setting her bag on top of a large speaker when she gets in? Or possibly on the tv?

After a few false starts it appears that the leather blackberry case that we were using caused the problem. Swapping that for a protective case without the magnet has seen the problem dissapear. My cunningly designed bubblewrap wallet has done the trick - maybe I have started a new trend.
