Hi I have an iPhone 2g jailbroken and unlocked on 3.1.3 and using AT&T as carrier. Recently I had to renew my minutes so I got the 75 dollar unlimited call and text with 200 Mbs of data right before that I used the last of my Mbs from my old package after that I relized I could not access my Internet and my network settings has dissapeared I had already been to unlockit.co.nz when I first got the phone and that aloud me to use my data but after a restore re-jailbreak and unlock and re-downloading of unlockit.co.nzs apn settings still no luck. Any suggestions???
