I have been trying to use tetherme for about a week now. I have a jailbroke iP4 on 4.2.1. I can connnect the phone to my mbp and get the blue tethering bar but no internet connection. I have tried rebooting, respringing, reset network setting to no avail. Everything appears to be setup correctly and working just no internet. I have searched for tetherme forum but have not found it. If someone could help me or point me in the right direction it would be much appreciated.
