I would like to be able to force 2G only to conserve battery life on my Captivate when I don't need 3G data speeds. Under Settings/Wireless and Network/Mobile Networks there used to be an option for forcing use of 2G networks only. This is missing on the Captivate menus. I tried using Any Cut to set the preferred network type under phone info to GSM only, but it will not accept the forced condition. Any suggestions?
