I did use the adaptor to cut the sim down, the first old sim cut and worked perfectly but then I did the working phone and this did not work as well and I then ended buying another sim card from the provider at £10 but they wont sell a micro sim unless you upgrade your account and this means a £20 a month increase from my present contract.
So not as sucessful as I hoped. Along with te issue of the phone seller having to refund the payment due to a paypal dispute this has not been a good experience.
Now I know the I phone 3 has a normal sim I should have gone down that route. So the present unused I phone 4 16g may be advertised soon.
