I have some real problems with how my tethering works. I have an iPhone 3GS on OS 4.1. My computer is a Dell running XP SP3. Generally, my service is Edge and not 3G. I can tether but I have two issues. If I call or receive a call I lose my tethered connection. When this happens I always have to reboot my computer to re-establish the connection. I can get around this particular issue by forwarding my calls to my wife’s phone, but it is definitely not the best solution. Also, if I lose my connection while tethering I have to reboot. This is a real problem due to the amount of time this wastes. I would not complain so much about just losing the connection occasionally, but having to reboot every time is a real issue. My cell service here is pretty bad, and there is not DSL or cable modem available. Is there a solution for this? I am paying for this, so I want it to work correctly. Is there some setting that I am missing on my computer or phone that would help?
