Hi, I have a problem with my iphone 3G that only occurred after updating to the new iphone software (4.2.1 i think). My phone will no longer pick up wi-fi connection. I am out of warranty with apple so it will cost over 200 euro for repair...not worth that. I have read on other forums that reverting back to the previous software version might fix this. The apple guy told me that this could not be done 'officially' but ...

So anyone know how this might be done?
