If you use a cell phone or other DEVICE, this is a must listen:

61. You're misstating the result of that study so badly I hardly know where to start.

First, I'm going to start by saying that that bit about celebrities is the most asspulled anecdata I've seen on this anecdata laden subject. Worse, it's using dead people's memory to enhance a fallacious argument because it can't stand without that emotional weight. You really ought to be embarrassed.

Second, you're badly misstating the results of the Hardell study, which is itself a bit dubious. For example, acoustic neuromas aren't cancerous but they sound scary if you don't know that, or that they're quite rare, occurring in about 1:100,000 people. Because of their scarcity you'd need an enormous sample to even have a statistically significant number of occurrences from which to declare an increase in frequency. Hardell's study used 12,000 people. Which is quite a lot of people but in that group you'd expect somewhere around zero neromas.

Third, Hardell's own results state that "Overall, no increase in risk of glioma or meningioma [the two most common types of brain tumors] was observed with use of mobile phones. There were suggestions of an increased risk of glioma at the highest exposure levels, but biases and error prevent a causal interpretation. The possible effects of long-term heavy use of mobile phones require further investigation." Translation: Hardell's own data ruled out an increase in cancer in all cases except in the heavy use data, which were not statistically significant enough to preclude wasting more time and money on yet another study.

However it should please you to know that more recent studies with even larger samples have settled the issue, and no, cell phones don't cause cancer. http://ije.oxfordjournals.org/content/42/3/792 "In this large prospective study, mobile phone use was not associated with increased incidence of glioma, meningioma or non-CNS cancers."
