TUTORIAL: How To Block Data on the iPhone

This is my first tutorial so I hope everyone can follow!

This is a simple tutorial that works on any iPhone and does not require jailbreaking.

Purpose:
Block data usage on your iPhone when you are not connected to WiFi.

Intended Users:
iPhone users who are not subscribed to a data plan.

Notes:
1)This will NOT block the usage of wifi on the iPhone. This is so that you are not charged for data usage of EDGE or 3G unknowing since there are no warnings on the phone.

2)I have never had any problems by using this method, however some users report being charged for data usage even after going through this procedure. The only sure fire way to block data is to call up your service provider and request that they block data on your account.

How To Block Data on the iPhone

Step 1
Make sure that you are connected to the internet through WiFi on your iPhone

Step 2
Open up safari and go to the url: unlockit.co.nz. It will load up a page called APN Changer.

Step 3
Allow the page to finish loading, scroll to the bottom of the page and hit "Continue".

Step 4
On the next page it will ask you to select the option you wish to use. Select "Disable Data (FakeAPN)"

Step 5
On the "Install Profile" page, just hit the "Install" button and then "Install Now". Hit the "Done" button after the installation is complete.

That is all you need to do!

Check That The Data Blocker is Working

To check that the data block profile is working correctly, turn off your wifi by going to:

Settings-->WiFi

And just toggle the WiFi switch to "Off"

Open up Safari again and hit refresh. If you get an error saying "Cannot Open Page", the data blocker is doing the job!

Remove the Data Block

If you would like to remove this data block at any time just go to:

Settings-->General-->Profile

And then hit the "Remove" button and "Remove" again to confirm.

I hope that helps some of you out.
