Update: If you have the latest version of iOS (3.1.3, 4.0, 4.1 or later), please check update below.
Vodafone(India) will not allow to use the regular GPRS plan (Vodafone Live) on iPhone. We need to take special iPhone data plan which costs min of Rs 199. This is sort of insane, So I just took a crack at it and found a way to access the internet using the regular plan. I have an unlocked, jailbroken iPhone which is running 3.0 firmware. Please follow the below instructions.
Using OpenSSH, edit preferences.plist located in /private/var/preferences/SystemConfiguration.
Important: Make sure you take a backup of the original preferences.plist.
Around line number 89 (this is appox line number, contents of the file may change based on your phone settings) replace the <dict> with below <dict>
<dict> <key>Interface</key> <dict> <key>DeviceName</key> <string>ip1</string> <key>Hardware</key> <string>com.apple.CommCenter</string> <key>Type</key> <string>com.apple.CommCenter</string> <key>UserDefinedName</key> <string>com.apple.CommCenter (ip1)</string> </dict> <key>Proxies</key> <dict> <key>HTTPEnable</key> <integer>1</integer> <key>HTTPPort</key> <integer>9401</integer> <key>HTTPProxy</key> <string>10.10.1.100</string> </dict> <key>UserDefinedName</key> <string>com.apple.CommCenter (ip1)</string> <key>com.apple.CommCenter</key> <dict> <key>AllowNetworkAccess</key> <integer>1</integer> <key>Available</key> <integer>1</integer> <key>Setup</key> <dict> <key>AllowNoDNS</key> <integer>1</integer> <key>apn</key> <string>portalnmms</string> <key>password</key> <string></string> <key>type-mask</key> <integer>1</integer> <key>username</key> <string></string> </dict> <key>Version</key> <integer>2</integer> </dict> </dict>

Update: The below configuration is working on 3.1.2 as well, but the line numbers are little different.
Update (16 Mar 2010):
Many guys have commented that the changes that were made in preferences.plist are lost after restarting the iPhone (for versions 3.1.2 and 3.1.3). So today i decided to take a look at it. And what you guys said is absolutely right, i upgraded my iPhone OS to 3.1.3 and i see that the settings are lost after restarting the phone. And you guys don't worry, i had found a way to fix this and this is much easier than my previous solution. Below are the step by step instructions.
- Download and Install iPhone Configuration Utility from http://support.apple.com/kb/DL926
- Open the application, Select Configuration Profiles on the left hand side menu and click New in the toolbar; Enter the name, identifier, organization and description; see the image below for more details
- Now go to Advanced option and set the apnname = portalnmms, proxy server =10.10.1.100 and port = 9401
- Connect your iPhone to computer via USB cable and you should see your iPhone in the devices menu on Left hand side. Select your device
- Select Configuration Profiles tab and you should see the Vodafone Profile; Click on Install
- You will see a pop on your iPhone asking for permission to install the configuration, Click Install button in your iPhone
- Turn on Data Roaming. Data Roaming can be turned on from Settings > General > Network on you iPhone.
- And you are done with the configuration. You should be able to use internet on your iPhone now. If its not working just reboot your phone.
Hope this helps !! Please feel free to give your Feedback, Suggestions
