Is anyone else having problems with their 3G connection under iOS 7? I have Sprint, and in my area they are currently testing LTE, but it isn't widely available yet. If I happen to find an area with LTE, it zips right along, but on 3G, I get absolutely NOTHING. No internet connected apps will recognize that I have even the slightest connection. Is this an iOS 7 specific issue? Anyone else experienced it? Any carrier settings fixes out there? Another weird thing: Sometimes I'll be in an area where I know I typically get an LTE connection, but it stays stuck on 3G. Occasionally, a hard reboot will cause it to switch back to LTE after the reset, but sometimes that doesn't work either. Weird.
