As mention in previous post:

“Maxis 3G/EDGE/GPRS Charge is Expensive!!!“

I found a way to disable the 3G or/and EDGE on your iPhone. You can enable it anytime you like if you need it.

Try out this application: BossPrefs (You may get it from Cydia for FREE.)

You can use this application to

- Disable/Enable 3G (Disable this to save you tons of money)

- Disable/Enable EDGE (Disable this to save you tons of money, since it charged the same rate as 3G)

- Disable/Enable WiFi (Any reason we need to do this? As far as I know, NO.)

- Disable/Enable Bluetooth (Good feature, why should I disable it?)

BossPrefs also has other useful features (tab on the More button on top) like:

-Fix User Dir Permissions (This will help to solve some application crash problem)

- Show Free Disk Space (To check your iPhone’s free space without go into iTune)

- Enable Numeric Battery (Show percentage of available battery instead of the green battry icon)

And, BossPrefs has shortcut to:

- Respring (restart the GUI of iPhone)

- Reboot

- Shutdown

Your iPhone (just tab on the Power Button on the bottom of the screen and you will get the menu).

I do feel this is a VERY useful tool. Let’s give it a try and see how good it is.

Thank you for reading.

I have a talk with my wife and found out that she actually not connecting to 3G purposely, but the application at background will request for a connection from time to time (when a page opened in Safari; Mail accounts setup in iPhone and by default it will check your mailbox every 5mins?), or she mistakenly press some applications that will connect to internet and get update by itself (Weather, Stocks, Maps…).

For those who use iPhone 2G/3G and you are not taking 3G unlimited package or the Maxis iPhone package, please take my painful “experience”. Think twice before you activate your 3G connection to surf on your iPhone.  Since Maxis 3G/EDGE/GPRS charge is DAMN EXPENSIVE!!!

There is way to stop the 3G/EDGE/GPRS connection to connect automatically when applications request. Please stay tune on my next post.
