I am jailbroken n unlocked. just cant get the 3g going. it worked perfectly with my 3gs. But in iphone 4 cant get to the edit apn setting whatever i do. its just that through wifi cydia opens without any pics on homepage. just question marks.AS suggested by i.Annie i tried to get a carrier bundle for my service provider but its not there. Also the edit apn tweak in cydia crashes while loading.
