Yes I am sure. I have extracted and modified the Carrier Configuration file on my
iPhone.
Are you using an officially unlocked 3GS or a jailbroken one? What Vodafone data plan do you use?
What I was talking about in my previous post is the APN on the Vodafone India Carrier Configuration file that is part of the stock iPhone OS. On carrier locked
iPhones the option to edit/modify your APN manually is disabled. So you are stuck with using the carrier (in this case Vodafone India) provided data plan which uses the APN "iphone". But the same option is accessible on factory unlocked or jailbroken iPhones. This allows you to manually set your APN and use whatever data plan you want to.
The APN you use will depend on the data plan you are using. The APN you mentioned "portalnmms" is part of the Vodafone Live WAP service. I am not sure if you can access everything with this APN, I cannot comment as I do not use this as my data APN. I use the Mobile Connect data plan and in my network settings I use "www" as my data APN and "portalnmms" as the APN for my MMS service. From my experience of Vodafone data plans, I can tell you that they usually charge you for all traffic over the WAP APN whereas their unlimited data plans use the "www" APN.

Thanks for your detailed answer. I have asked Vodafone to unlock my set but they said they cannot do that.
I would like to go with your second option. Let me know how to proceed and whether there is any risk?
Hey.. Sorry about taking so long to reply. I've been swamped with work and havent had a chance to log on to the forum in the past few days. Here's my response to your query....
There is always a certain amount of risk when you are modifying files on your phone. But you can mitigate the risk by creating a backup copy of the files before you modify them. If the changes you make don't work then you can always replace the files with the backup copy.
To start off what I suggested, you would need a program like either Phone Browser or Total Commander. I use both and they work. You will also need a plist editor program. This is basically an editor which will allow you to open and edit property list files. You can
google and try to find them.
Once you find and download the programs, follow the steps below...
1. Install the programs on to your computer.
2. Connect your iPhone to your computer then launch the Phone Browser or Total Commander program.
3. Once you see the directories/ files on the iPhone, go to - System/Library/CarrierBundles 4. Look for the folder named Vodafone_in (it should be somewhere at the bottom of the list) 5. Save a copy of the Vodafone_in folder on to your computer. Create a backup copy of the folder.
6. Launch the plist editor program and open the file named "carrier.plist" (this file will be in the Vodafone_in folder that you just copied to your computer).
7. In the above file look for the section which lists the APN. It will look like this:
apn
iphone
8. Delete the word "iphone" and replace it with "www", without the quotes. (www is the APN for Vodafone Mobile Connect). It should now look like this:
apn
www
9. Scroll further down in the file and you should see the APN setting listed again (this I for the tethering option). Change it here also.
10. Save the file.
12. Go to the Vodafone_in folder on your iPhone. Delete the carrier.plist file.
13. Copy the file you just modified from your computer to your iPhone in the Vodafone_in folder.
14. Reboot your iPhone.
15. Insert a Vodafone SIM card which has Mobile Connect data plan activated and test to confirm that data services work. Try accessing a website thru Safari.
Hope this helps. Let me know how it goes. I have done this not only on my iPhone but also on several others. So this should work for you too.
