Wife and I both got iPhone 6s last week and iOS 8 was crashing apps a lot more than either of our previous iPhones and, the wifi was dropping out occasionally. We thought iOS 8.0.2 had a fix for this as well as other known issues but as stated in this thread, the wifi drops persist. While preparing dinner last night my wife was watching a show on HBO GO on her iPhone 6 (which was connected to our home network as usual and as always when we're home) and she gets a message stating that using 3G to stream may impact our data usage and bill. So, although the iPhone's wifi status symbol showed in the top left corner as if her phone were still connected to our home wifi, the phone was apparently using our cell's 3G connection to stream HBO GO. Horrible! iOS 8 so far has been a disaster compared to my usually great experiences with previous iOS versions. Apple's gotta get on this! While her phone was apparently using 3G instead of our home network to stream HBO, I was in the living room streaming Netflix via Apple TV with no problems whatsoever. So, we know for sure that it's not our network. We've thankfully never had any network issues with any of your previous iPhones nor either of our two Apple TVs nor my MacBook Pro. It's the Phones themselves or the iOS that's the problem. iOS 8.0.3 had better be in the works with a legitimate fix for the wifi issues and whatever other issues remain. C'mon Apple.
