i have an iphone 3g jailbroken on 2.0.2, i am currently using x-sim and have unlocked it to use vodafone uk in the fon, everything works fine except wap. I have gone to settings > general > network > cellular data all i see is apn ,username and password which i have entered, but i want help on where to find the advance settings like default gateway and all the rest to enter the other settings

Thank you
