First, post the obligatory power lines don't cause cancer bit .
The US has spent the equivalent of one billion dollars by 1990 to research this link, despite more recent studies now suggesting a 'possible' correlation, there simply isn't enough evidence to suggest that power links do increase the risk of leukemia.
Then drive in the kicker. The radiation/EMF from high power lines is much larger than that from mobile phones. If power lines, electrical equipment doesn't cause cancer, the much more minute radiation from cell phones won't. Now, there is a difference, since inverse square law will tell that inverse square law will suggest that constant exposure to radiation, like say your mobile close to your crotch would make up the difference. But that aspect will allow you to shut down the cell tower/wireless signal aspect of the argument.

The last bit is about numbers, how correlation doesn't equal causation and how virtually everything has been lumped as carciogenic.
The new studies are follow up of the original studies done since 1990 and the problem remains the same. You can find potential clusters in any population group.Is it statistically significant? Not all, but even for those that are, its just too diffuse to separate out any cases, to the extent that possibly 2 out of 500 cases may be caused by power lines.
The IARC classifies any carcinogen along this category.
Group 1: Carcinogenic to humans
Group 2A: Probably carcinogenic to humans
Group 2B: Possibly carcinogenic to humans
Group 3: Unclassifiable as to carcinogenicity in humans
Group 4: Probably not carcinogenic to humans
A common joke is how water is the only chemical placed in Group 4.
Mobile phones possibly causing glioma, a rare brain tumour falls under group 2B. Which is where virtually any other potential carcinogen falls under. Group 2B does NOT indicate that phones cause brain cancer. That classification is filed under the category "We need more funds to see if this is a potential carcinogen".
Glioma itself is even more likely to be due to chance, due to the rarity of the disease. Its entirely possible that the significance was due to chance, especially since there are other studies which don't show a link.
As long as the IARC/WHO/NTP doesn't put it as Group 2A and etc, there simply no point in investing effort about this. Any potential risk would be so small that its insiginificant. For example, the phones cause glioma means that its a potential 2 cases in increase.Taking that ONE singular study which bumped it into the 2B cat. That means increasing the risk of brain cancer, from 2 cases per 100,000, to 4 cases to 100,000.So, even if we ignore all other studies, that's only a potential 6 thousand increase in cancer cases and this is assuming that all 300 million subscribers in the US are exposed to enough radiation from mobile phone usuage to be affected.
Granted, all of this ignores the fact that phone radiation do affect the brain and metabolism but the potential risks are simply too small for any reasonable person to bother. Living in a naturally radioactive environment such as radon or even frequent jet travellers who might be exposed to higher doses of cosmic radiation is more significant.
