Posted By Robert K Lewis I understand some of the cases do contain nickel and this is a sensitiser to some people. It used to be a problem before the days of tights for some women but I say no more!!:-) Try the black plastic case version if it is the metal version being used. Otherwise no ideas at all. Bob

Posted By Chris Packham Bob Rather than having to buy a new Blackberry, if it does have a metal case you can test to see if this is releasing sufficient nickel to cause an allergic reaction. This is known as the dimethylglyoxime or nickel spot test and is available commercially for a relatively small sum. Just Google chemotechnique and the appropriate website should come up. I use this test regularly in skin exposure risk assessment work to establish whether workers are being exposed to nickel. Just try it on a one pound coin to see how much nickel this releases! Chris
