I would like to ask does anyone know how to disable the data/edge of iphone 3.1? The method for 3.0 not longer working for 3.1

) Open settings app and disable Notifications. These appear directly under carrier, if you have them. They only appear if you have installed an appstore app that requires push. If you don’t have these, skip this step.

2) Disable push mail fetch.

3) Disable EDGE using SBSettings

4) Load settings app, enable airplane mode. Wait at least 10 seconds.

5) Load settings app and disable airplane mode. Wait for you to get service again.

6) Load SBSettings. You should have no Data IP (IP N/A).

7) Try using safari on Data. It should fail. Wait a bit, Load SBSettings your data IP should remain N/A.

does not work anymore.
