Found another way to disable Edge/3G on iPhone 另一方法让您的“爱疯”锁掉运用手机Data

Found this app at iClarified to disable Edge/3G om iPhone, would like to sharing here.
Hope this will help up who are having the same suffering as my previous post.
Actually mine have solved with the setting as last time, this maybe the 2nd secure on it.
*Below instructions was from iClarifired.

These are instructions on how to block and disable Edge and 3G data usage on your iPhone using the SBSettings Data toggle.
Anderson Vulczak and BigBoss constructed the toggle which sets a bogus IP address, (1.1.1.0)[127.0.0.1 on mine] to your data adapter’s IP address. This seems to kill EDGE / 3G without any battery drain issues reported in using other methods such as entering a bad APN.
You may want to do this to ensure your iPhone does not rack up costly data usage chargers from your carrier.

Step One
Press to launch Cydia from your iPhone Springboard.


Step Two
Select Sections from the tabs at the bottom of the screen.


Step Three
Select SBSettings Addons from the list of Sections


Step Four
Choose Data Toggle from the list of Packages.


Step Five
Press the Install button at the top right of the screen.


Step Six
Press the Confirm button to begin installation.


Step Seven
Once installation has completed successfully press the large Restart Springboard button.


Step Eight
Swipe your finger across the status bar to pull up the SBSettings menu.


Step Nine
Press the Data toggle to deactivate data.


You will notice the icon goes red and your IP Address changes to 1.1.1.0.

mine was 127.0.0.1


Edge and 3G data access on your device is now blocked.


另一方法让您无忧无虑的享用您的“爱疯” wifi 无线上网，不用再付钱。
