If you accidentally upgraded your iPhone to OS 3.1.3, like I did, you will notice that the peacefulinsanity and help.benm.at mobileconfig no longer work. Well here is, the only way, to enable iPhone tethering again for ATT customers:
- Use the http://spiritjb.com/ to jailbreak your phone
- Go into Cydia and install MyWi with Rock
- Sign up for a free Rock account then turn on MyWi
- You will now have tethering enabled, but here are the rules:
- Do not uninstall MyWi or Rock, it will disable your tethering
- Do not open the MyWi app again, or you will have to buy the app – This is really the trick here. I just hide MyWi and Rock on a different page so I never turn them on again. If you don’t turn it on again, it won’t know that you have expired your free trial. This way you can have tethering permanently.
- You should turn off the Wifi since it will drain your battery
- Tethering will ALWAYS be enabled. You can’t turn it off with this hack. But do not worry, I can last a whole day without charging even with tethering enabled all the time
