Is your smart phone making you itch? Approximately one-third of all Blackberries contain nickel, one of the most common allergens that causes contact dermatitis, according to new data presented at the Annual Scientific Meeting of the American College of Allergy, Asthma, and Immunology (ACAAI).
Researchers analyzed 75 cell phonesÃ¢â‚¬”including iPhones, Droids, Blackberries, and flip phonesÃ¢â‚¬”in search of models containing two common allergens, cobalt and nickel.

What that looks like: dry, itchy patches of skin along your cheekbones, jaw line, and ears.
