I have a jailbroken iPhone 3GS on ios 5.0.1. I need to change the apn settings. I know I could use unlockit.co.nz, but I want to be able to have mms, and be able to see the "cellular data network" tab, under "network" in the settings menu of the phone.
I know there used to be something called "TetherMe", and "TetherMe APN Editing" in cydia, but whenever I search TetherMe in Cydia, it says it costs $4.99 (it used to be free because I've done this before on other iPhones).
I've tried the whole T-Mobile sim swap when on the "network" screen in the iphone to try and get the "cellular data network" tab to come up, but nothing is working. Please let me know what I can do.
