I have done a search already and it seems there arent many people having problems with tethering, just alot of people talking about getting it working. So I have a jailbroken 3g on FW 3.0 on ATT network and have a mobileconfig from help.benm.at. I originally tried tethering on T mobile and the phone showed up with the blue band and said it was tethering my computer (running 10.5.7) but safari didnt have a connection. I thought it was a tmobile issue so I put my ATT sim back in, deleted the tmobile settings, reinstalled the mobileconfig for ATT and it still is not working. In fact I dont even get the blue band anymore and it seems it is having a a problem even making the bluetooth connection. The phone says it is not connected. I have tried usb and the computer doesnt even recognize that it is plugged in. Can anyone help me out here. I'm afraid I %ucked something up.
