If you’re anything like me, sometimes you need to tether but never enough to justify the added expense. FlashArmyKnife allows you to do just that. It’s pretty simple too. Just watch the video for a decent walk through. You’ll need this too:
Enter this to Activate Tethering (no commas):
1642, M+, C, 1452, M+, C, 1943, M+
When it says “run”, tethering is running. Press “C” to stop tethering.
It’s worth mentioning this does violate TOS with your carrier, but if you’re wanting to do this kind of thing you probably already knew that.
