Has anyone been experiencing a problem like this? Since earlier in the week when both 3G/4G was down for about a day. The following day 4G was up but 3G was still down. Like many of you i usually turn 4G off and use 3G to conserve battery. So since the beginning of the week my 3G has been down and I've been forced to use 4G which can sometimes be spotty. I want my 3G back! This is in the SF bay area btw.
