Disabling EDGE on 3.0 firmware

Disabling the EDGE from SBSettings or BossPref was not working on my Iphone 3GS with 3.0 firmware. It was reenabled quickly because 3.0 is configured in that way. It took me some time to realize that my phone bill was getting higher each day. So I had to call the call center or my carrier, and i asked them to cancel my EDGE/GPRS internet on my phone number.

The worst thing is if you try to enter invalid APN settings for the internet, becouse 3.0 firmware tried automaticly to enable the enternet, and as a result of this the battery dies for less then two hours even if it was fully charged. Searching for a solution, i found one on BigBoss’s website, and it worked for me so i decided to share it with you. Here is what you have to do according to them:

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.

Feel free to test this. If you get a Data IP address, you have indication that your Data may be getting reenabled. I am interested in the results of this.

If this works for you too, soon they will upgrade their software so you can forget about this steps, and start using the toggles once again.
