What I used to do is , hit the green button for calling and put the cell to my ear straight away . According to my pal Sunil , the maximum amount of cell readiations is during call handshake. So how do I avoid all those radiations? Simple, know the signs S60 provides. I learnt this one from my wife, from call initiation to call connect S60 shows different symbols to indicate the process. So simply keep the cell away from the ear till you see the call connect symbol , heres how it looks
Call (dont know what to say) , ring going :
Call connected :
Oh, forgot to say, I mostly do not carry my hands free along otherwise its a good solution too.
