I am loosing my 3G connections about every 3-4 days. I am on CDMA only as I don't have 4G in my area yet. Not sure what I am doing, but I just opened an app and it told me there was no connectivity. Indeed the 3G connection icon was gone. I can get it back by toggling Airplane mode. It doesn't happen that often so I am not that concerned - yet. Has anyone else seen this problem? Thanks!!
