I have an AT&T (Cingular) (HTC) Tilt with Windows Mobile 6. There’s some extra charge for tethering, I don’t know anything about that. This is kind of like the GPS in it they want you to buy Telenav or something, but it works out of the box with google maps mobile if you download it. I used the QuickGPS in the control panel somewhere to make it gps-lock faster, but that’s another converation.
Anyways, I have a laptop with ActiveSync 4.5 installed running XP Pro SP2. When I connect the phone using USB, activesync wants to sync it, which is slightly annoying because it only supports profiles for two computers, so syncing to my home desktop, work desktop and laptop is a no-fly zone.
ipconfig will show a 169.254.x.x address with no dns and the gateway pointing back to the computer with the phone I believe as a dhcp server
Anyways, if you use File Explorer on the phone to navigate to \Windows, you’ll find ‘Internet Sharing’. I haven’t figured out how to make a menu option yet, I assume there normally is one but it’s removed as Cingular wants to get that extra fee out of you. If you run this, leave it on USB and Medianet and hit connect, you’ll see it disconnect on your laptop and Windows will redetect it as a as windows mobile based internet sharing device.
ipconfig will now show a 192.168.0.x address with gateway/dhcp/dns of the phone. I assume it’s NATing. Cisco AnyConnect SSL VPN works fine through it at least, I haven’t tried anything IPSEC based though.
It looks like activesync doesn’t see the phone anymore, I figure we need to choose disconnect in Internet Sharing on the phone to make the usb cable go back to normal mode.
