why is the celluar data and network configuration menus still blocked in my legally unlocked iphone 4?
I recently switched a prepaid carrier, airvoice wireless, with my iphone 4. AT&T granted me an unlock which worked successful in itumes after the restore. I should now be able to see this pathway Settings > General > Network > Cellular Data Network, which I need to edit in order to use cellur data with my new service. AT&T hides these settings, but usually an unlock results in unhiding them according to internet accounts. I tried downloading the approriate APN profile from http://unlockit.co.nz/, but this did not work for me either. I need to edit the MMSC, MMS, and APN to be able to use cellular data with airvoice wireless. Any advice?
iPhone 4, iOS 6.0.1
