None of these worked, the phone worked fine at 8.0.1. Upgraded to .2 as we'd heard there was problems with .1 and then the LTE service dropped to 4g, out Iphone 5 with .2 works fine but the 6 plus is not working. correctly. It sticks to 4g and drops in and out of service frequently. I'm not going to reset to factory settings as the latest backup for the phone was when we got it (2 days ago) and I really hate to lost all the stuff we done to it.
until I know that a full factory reset will actually fix it, I'm not going to do it. Apple needs to fix this now, it's bee an issue for a few days according to what I'm seeing on the forums.
