Hi a purchased an o2-uk iphone and then had it jailbroken. the phone runs 1.1.2 firmware. the iphone accepts all o2 sims but i have purchased a sim adapter which lets me use my kenyan and other sims in the iphone. i would like to know how to get the option to configure my iphone for GPRS/EDGE settings. the option isnt there already under settings. any help would be most gratefully received.
