Dunno about cellphones,, UK legal CB pushes out 4watt on the 27mhz wavelenghth ( i think its 11mtr band FM)
Pointless info
With reguards to using your cell phone as a modem, you would just need a phone with a modem in (duhh) like the nokia 7110, a data cable capable of transfering internet signals (or Infra red, doubt amiga uses that tho), and basically install the phone as a modem with a driver.
Hope this helps, i do it on my lappy often.
