Well I don't have an Android phone as you can probably see on the side bar so bear with how much of a noob question this is. How can you tell how much signal you have for 3G or 4G if there is only one signal bar in the corner? For instance, my EnV Touch has a signal icon for EVDO and one below it for 1X. How can you tell the difference on an Android phone if there is only one signal graphic that just shows whether you are connected to 3G or 4G?
