I have a jailbroken 3.1.2 iPhone 3GS. The carrier is Fido. I only have a 500 MB data plan so Fido will not officially enable tethering for me. So I looked into doing it myself.
I tried the bspatch method (Enable Tethering on iPhone 3.1.2 - ONLY 3G & 3GS) but it didn't work - probably because I couldn't find a proper mobileconfig for Fido. When I tried to enable tethering, the phone said please contact Fido to enable tethering.
Can anyone help me?
