I am on the Fido network in Canada. When I upgraded my iPhone to 3.0 iTunes had to download a new carrier config for Fido. Maybe that's what enabled tethering? Does Vodafone officially allow tethering on the iPhone?
Just turning the switch on will not connect it to your laptop and tether.
Not sure how you're trying to tether, but I can tell you how it works in XP.
After you've paired your computer with the phone, you right click on the little Bluetooth icon in the system tray and click on join Private Area Network (PAN). Then you'll see your iPhone available, so click on that, and you're off tethering.
I have tried several carrier SIMS and the appropriate settings..
The problem is - the phone does NOT send a DHCP IP address to the computer..
Internet Tethering works ok both on BT and USB - the blue line appears, and the phone says it is tethered, but there is no IP given to the computer thus NO DATA will pass...
Help please ... what have I forgotten -- BTW it is jailbroken, will this affect things??
I KNOW that.. (but thanks for trying). I do run a wireless ISP..
THE problem is the iPhone does NOT PULL an IP from the network..
It may be an issue with my iPHone or UK networks - I have tried DHCP and several SIMS and none DHCP an IP
HOWEVER I have solved it.. The clue is actually in Apple's help!!
Set the computer the iPhone is connected to to the following STATIC IP
IP - 192.168.20.2
Mask - 255.255.255.0
GW - 192.168.20.1
NOW all you need is a DNS and OPENDNS works nicely..
