Okay, so you want a better source.

"Here is a common-sense personal view from a physician and parent of four children who is also a major user of wireless devices of all kinds."
"New reports continue to be published several times a year, suggesting that there might be health risks from mobile phones electromagnetic radiation. There can be no doubt any longer that mobile phone radiation affects living cells. For example research shows that nematode worms exposed to mobile phone radiation produce more eggs, release stress hormones and grow larger. "
"[]at present the clear evidence suggests that if there is any effect on human health at all from use of a mobile phone, the electromagnetic radiation risk is very, very low for the individual user."
"For example, in October 2004, scientists at the Karolinska Institute in Stockholm gave a new warning about mobile phone radiation and brain tumours - accoustic neuromas [] They found that long term users of mobile phones were four times as likely to develop growths on the side they held the phone, and twice as likely as non-users to develop these benign non-cancerous growths."

"March 2003 another study in the International Journal of Oncology suggested that mobile phone users had a 30% increased risk of brain tumours - mainly accoustic neuromas - which occurred close to the ear used for mobile phone listening. Previous studies had shown that growth of leukaemia cells could be increased dramatically after exposure to mobile phone radiation. Although accoustic neuromas do not metastasise (jump to invade other parts of the body) they can create serious problems if intreated. The early symptoms can be hearing loss, loss of balance or noises in one ear"

"GSM and GPRS (2.5G) phones use what is known as pulsed radiation. The levels rise and fall very rapidly. 3G phones on the other hand use continuous levels. Some research suggests that pulsed radiation may have a greater effect on cells than constant exposure"
