iPhone: How to restore 3G data after upgrading to iOS4

Sometimes, the process to upgrade iPhone to iOS4 corrupts the configuration for 3G data. You can see a 3G icon on the status bar, but all apps requiring Internet report that there is no connection. This problem don't affect WiFi connections.


These are the steps I followed to restore the 3G data connection:

1. Download "iPhone Configuration Utility" from Apple site:

2. Run the "iPhone Configuration Utility" and select "Configuration Profiles" from the left sidebar.

3. Click "New" on the toolbar.

4. Fill the "General" section with a name, identifier and description of your choice for the profile.

5. Fill the "Advanced" section with the details of your phone carrier. For Telcel (Mexico) I provided these values:
- APN: internet.itelcel.com
- User: webgprs
- Password: webgprs2002
- Proxy: 148.233.151.240

6. Connect your iPhone using USB and select it on the left sidebar.

7. Go to the "Configuration Profiles" and click 'Install' on your profile.


And done, you must have now 3G data again.
