I've just fired up my new GiffGaff SIM in my Galaxy S 2. It asked me if the service was O2 UK Postpay, O2 UK Prepay or Tesco.
I assumed the middle one, wonder if it makes a difference, next time I update my firmware?
neither - you need to download the giffgaffapn app from the android marketplace:
do this via wifi, and it will set your phone up correctly for internet.
u can choose O2 prepay. but yr internet will not work coz its going to add the O2 settings. u need GiffGaff settings

Thanks for the answers guys. I got the service message and settings shortly afterwards so I imagine I won't see this setting choice again until next time I factory reset.
you need pre pay but it actually dosent matter at all
