Sprint Touch tethering with Lenovo Thinkpad problem

[Procter]

Anyone is using Thinkpad to tether with Touch? I have successfully tether with Touch using the mods here, there's one problem I could not solve. Since the "internet sharing" configuration uses "automatically get ip & DNS" so basically without messing with the internet settings, it can get online, however the Thinkvantage Acess Connections cannot manage a profile specially for windows mobile device. When my phone is in internet sharing mode, the computer can detect the phone as a internet sharing device, if I set up a new profile at this moment it can be applied normally, it would be showed as "wired ethernet". But when the device is disconnected, the profile I set up just now will change to ethernet only, only the ethernet card would be listed in the device, but the windows mobile device disappered. If I tried to use this same profile to connect, it would simply tell me ethernet cable unplugged, connection failed.

Anyone knows how to use access connections to manage tethering device, please give me some hints. Thanks.
