Stephen, are you using anecdotal evidence or do you have actual data on migraines and cellphones?
I did a PubMed search of “cellphones” and “migraines” and got 3 results 1 of which was valid.

"Headache and migraine
In total 33 studies with investigation periods between 1992 and 2006 were identified (Table 4), 24 of these from Europe (Netherlands, Italy, Sweden, Spain, Denmark, Finland, BRD, France, Great Britain), 7 from the USA, and 1 study was performed in Europe and USA. To obtain data from Canada, also, 1 study from 1992 was included (O’Brien et al., 1994).
In 10 studies prevalence for both headache and migraine were given while another 10 focused on migraine only and another 13 on headache only.
The studies show very high differences in their results for prevalence depending on the studied type of headache and/ or migraine. Prevalence for headache varied from 2% to 84%, for tension-type headache from 2% to 89%, for migraine from 4% to 30%. Lyngberg et al. report a 100% lifetime prevalence for headache (Lyngberg et al., 2005). Over the 14-year period reviewed it was found that frequencies differed according to definition of disease or complaint and gender but did not show any systematic increase or decrease. It was also noted that both headache and migraine were detected more frequently in women than in men (Michel et al., 1996; Launer et al., 1999; Lipton et al., 2001; Prencipe et al., 2001)."
