Does anyone know how to turn off 4G after the ICS upgrade?
The method I just used was.....pull down the notifications shade, click on quick settings, click the little gear for the settings menu (this all can also be done by just hitting menu from the home screen and pressing settings) then click on the mobile network logo - NOT the mobile network toggle!! Then you'll see the option for network mode where you can choose from 4g/ cdma, or just cdma. Hope this helps.
