The original article is online at the British Medical Journal. And it is actually just a lettor to the editor, not a true article. The journal's home page is at http://www.bmjjournals.com/?ck=nck and a little searching will get you to the proper article, except you need a subscription to read the full letter.
Some comments present other anecdotal evidence, others question the effects of other items like iPods or jewelery. The best response (IMHO) is the last one, which includes the line:
"I would wager more people have been struck by lightning whilst picking their nose than whilst on a cellphone, it doesnt mean there's a link between the two."
and the disclaimer:
"Competing interests: Actually knowing something about physics, cellphones, and lightning" :-)
