Turn off 3G?

[will873]

Is there a way to turn off and on the 3G. I have an iPhone 3G and want toget the Captivate, but normally I can just turn on and off 3G to save battery life. Is this possible with Captivate? Thanks in advance.

APNdroid can do the trick, but it only turns off 3G/EDGE/GPRS all at the same time, and not just any of those 3

This is the only solution I've seen and I can confirm that it works.

From the main menu of the ServiceMode screen, select DEBUG SCREEN, then PHONE CONTROL at the bottom, then UE STATE CONTROL. From there select CHANGE RAT TO WCDMA to enable 3G only, and select CHANGE RAT TO GSM for 2G only.

Doesn't survive flight mode or reboot though.
