Default Cingular 8700c on T-Mobile Modem Setup

Please Login to Remove!

My first post so I hope this is good! It works for me so let me know how it goes. I used a lot of info from this board to get this working, so it's nothing new, but I know a lot of people here use t-mobile with there 8700c's so I thought my experience could help out. I've tried this on two phones on two computers so it's been pretty successful for me.

1. Make sure you have TCP access (Google local works, Rambler, etc...)
2. Install Blackberry Desktop and update if you want to.
3. Connect your Blackberry
4. Run Blackberry desktop and make sure you are connected. Do NOT Disconnect.
5. Goto "Control Panel/Phone and Modem Options"
6. Click "Modems" Tab, Select "'Standard Modem" Click Properties
7. Click "Diagnostics" Tab, then "Query Modem" you should get a bunch of commands and responses back, not an error. If you get an error make sure Blackberry desktop is On and Connected.
8. Click "Advanced Tab" and enter AT+CGDCONT=1,"IP","" in the "Extra initialization commands" box.
9. Click OK until you are out of everything. Leave Blackberry Desktop On!!! It's important!!
10. Goto "Control Panel/Network Connections" and click "Create a new Connection"
11. Press Next, Connect to Internet, Setup My Connection Manually, Connect Using a dial-up Modem, Enter Some name for the connection I used "EDGE", Phone Number should be *99#, Leave username and password blank, uncheck the default internet connection if you'ld like, and choose if you want a short cut on the desktop on the next screen!
12. You're almost done, A popup appears asking to Dial. Do NOT dial yet, click on the "Properties" Button.
13. Click the "Network Tab" and Double Click "Internet Protocol (TCP/IP)"
14. Click the "Advanced" Button and Uncheck "Use IP header Compression"
15. Click OK out until you hit the window to dial the connection
16. Click "Dial" and now you should be able to connect!
