I followed band unlock procedures here:
After putting in the sim card from Ting, it connects to T-mobile's network and I am able to make calls and texts, which is great.
However, I am unable to use data over the network. Ting has its own apn settings, which I have tried to enter. But after I add the apn in apn settings, the page remains blank and I am unable to select the apn that I have added.
To get around this, I have tried replacing /system/etc/apns-conf.xml with one I created myself with Ting's info, reset apn to default and reboot. Unfortunately, the phone still isn't connecting to data, and the apn page in settings remains blank.
So does anyone know what I should do? Would flashing a different rom help, is this a cyanogenmod issue?
