Great on Vista Thanks!

Hi all. First great Thanks to Sergey123456 for the Driver...

I will explain what I did on Vista Business (Retail edition) and how it worked for me, so it will be helpful for people that had problems.

1. On the PC: Open WINDOWS MOBILE DEVICE CENTER, go to Connection Settings and uncheck Allow USB Connections . Doing this will prevent Sync while you are using the 8525 as modem.

2. On the PDA: Open the WIRELESS MODEM program. Select USB as Connection Type. Go to MENU and select APN Settings, and assign wap.cingular.

3. Connect the PDA with the PC with the USB cable. Since you have disabled USB Sync, it will not produce any action on the PC for now.

4. On the PDA/WIRELESS MODEM, go to Menu and select START. This action will produce that VISTA will recognize a new device called "Generic Serial". Wait until the PC says that it could not find the proper drivers. Now, when it says that you will manually look for the drivers, select the USB MODEM Drivers posted on this forum. This will install the new drivers. It takes like a minute and now you will have 2 new devices:

Generic Serial --> HTC USB Modem

Modem Audio Device --> Unimodem Half-Duplex Audio Device

5. Now go to Control Panel, and Select Phone and Modems Options. Then select the Modems tab. There you should see the new HTC USB Modem and a COM assigned. Select PROPERTIES. Click on the Advanced tab. Type AT+cgdcont=1,”IP”,”wap.cingular” into the Extra initialization commands field.

Click on OK. (some people use isp.cingular instead).

6. Now create a new Dial Up Connection. Go to the START Button, select CONNECT TO. On that window select "Setup a connection or network". Choose "Setup a DialUp connection". Select the HTC USB Modem from the list (NOTE: You must still have the PDA connected and the Wireless Modem program up). On DialUpPhone = *99# Type WAP@CINGULARGPRS.COM in the User name field (some people use ISP@CINGULARGPRS.COM). Type CINGULAR1 in the Password field. Press CONNECT and it should work!

7. You should see the Connection Send Data and Recieve Data black squares on the PDA Wireless Modem program light up. This means you are connected!

Notes:

- If the PDA itself is connected to the Internet through 3G, all this will fail. So disconnect first.

TO BE ABLE TO SYNC AGAIN

1. Disconnect from the Wireless network on the PC

2. Stop the Wireless Modem Program (Menu - Stop)

3. Go again to 1. the WINDOWS MOBILE DEVICE CENTER on Vista, go to Connection Settings and CHECK Allow USB Connections . And you are back to normal and your PDA can sync again :)

IF SYNC FAILS OR CONNECTION WITH THE PDA FAILS TRY THIS

Some people might find problems caused by the USB HTC Modem drivers installation

1. Having still the PDA connected via USB.. GO to Control Panel, select Device Manager.

2. Find a device that has a Exclamation sign called "Windows Mobile Device". Right-click, Select properties. Select UNINSTALL the device.

3. Close the Device Manager

4. Unplug the USB cable from the PC for 1 minute

5. Plug the USB cable again to the PC (still having the PDA on the other end)

6. Vista will try to reinstall the Pocket PC Drivers (NOT the USB Modem ones) that will be found automatically by Vista.

7. All back to normal :)

Wish it helps!
