Thats great that your update to 8.0.2 has been working great, but as i go back and look at your posts you say that you don't have a wifi issue.
8.0.2 was a patch for cellular connectivity, touch id and the health kit app, not for the wifi issue a lot of people are having with this wifi problem including myself with 3 new iPhone 6's plus a replacement iPhone 6, and not just on my home wifi but every wifi router that i try to connect to, even the apple store wifi router, thats the reason they replaced my new iPhone because they watched how the iPhone reacted to their store wifi.
Maybe i should switch to Verizon, My phones are on AT&T's network and i can't do anything web based with it, i'll just keep bringing them back to apple till i get what i paid for, an iPhone that works correctly, my phones have not worked from day one, and i bet a lot of others haven't worked from day one but we were all probably rebooting our routers and modems for 3 or 4 days not realizing that wasn't the problem, its apples problem with software or hardware or a combination of both.
and they still haven't addressed the problem
