Wm5 smart phone d600 Internet sharing settings

Today, I am doing things at home. I want to visit some materials online, so I have to find a way to access the Internet through my mobile phone. I have been studying it for a long time and I have not succeeded. I tried it today and finally succeeded.
My mobile phone has reached d600 + Windows XP. I think this method should be suitable for all wm5.0 smartphones, but I have no chance to try it.
Follow these steps:
1. Operate the mobile phone: Start Menu->Program-> Internet sharing-> after selecting the connection method (WAP on my machine), dial-up connections
2. Connect with USB cable. At this time, Active Sync does not display the connection status, but displays a NIC that is requesting an IP address. After a while, the obtained IP address is
Assign by using the dhch Service
IP: 192.168.0.102
Mask: 255.255.255.0
Gateway: 192.168.0.1
DNS: 192.168.0.1

In this step, you are connected to the Internet normally. 192.168.0.1 is your mobile phone, which is equivalent to an internet server. Of course, there is no problem accessing the Internet through the mobile phone at this time.
3. The last step is to set the IE tool menu> Internet Options... -> On the connection page, click "LAN Settings", set "Automatic Detection" and "script configuration" to "unselected", and select proxy servers.-> click "advanced, set the HTTP Proxy Server to port 80 10.0.0.172 (in fact, this setting should be the same as the proxy set on the mobile phone, if it is directly using GPRS cmnet to access the Internet, it will be unnecessary. I use cmwap to access the Internet (6 RMB 50 m plan per month, poor people ~~), Configure the HTTP website through proxy)
