Anybody else wish they hadn't downloaded and having problems with 4.3.1? My iPhone4's Safari is running, maybe, half as fast as 4.2. I'm losing wifi connection in my house constantly. I've entered and re-entered my router password when prompted repeatedly. I even tried resetting network settings to no avail. My iPad1 is much, much slower. Internet is now even slower than my iPhone. Having problems playing video. Ugh. Have been a fan of Apple and had no problems with phone or iPad until now. Hugely frustrated. Would like to toss both out the window right now. Any suggestions? Is it time to go to the Apple store? But what will I say, It's just not as good as it was?
