I can add another item that may be susceptible to cell phones. My mother came to visit two weeks ago and she kept having problems getting into her hotel room. After a little experimentation, it appeared that her cell phone was affecting her electronic room key. Her room key failed three times when she kept her key in close proximity to her cell phone. After placing the suspicion on the phone, she kept her key out of her purse where she kept the phone. After that, there were no problems with the key.
We did no formal experimentation to determine if this was a coincidence or causality. She has also not reported any problems with the phone affecting any other cards with magnetic strips, such as credit cards. The evidence against the phone is only circumstantial and has not been verified.

The title of the article is "Mobile Phone Induced Circuit Failure." Abstract: Cases of circuit failures caused by mobile, or cell, phones are starting to be reported. A brief overview of the problem is given followed by a simple test procedure to gauge the risk to a product.
