Okay, before I start, please don't flame me for starting a new thread on a subject which has clearly been covered, at least partially, in other threads. I just wanted to summarize my experience with a new iPhone 5 and issues related to DATA connections. The PHONE connection seems to be perfect...no dropped calls, clear audio, etc. The problem is not having reliable data connections. My wife received her white 64 GB AT&T iPhone 5 from on September 26th (after ordering on the 14th from Apple) and she has had recurring problems with her data connections. Specifically, it will find wifi networks and even connect to them, but then it will spontaneously lose connections and she'll get error messages out of the blue saying that she's not connected to a wifi network. Also, while she often has 4 or 5 bars for her cellular signal, the LTE, 4G, 3G, or Edge indicator is often blank. Sometimes, LTE will light up and she'll be able to download at super-fast speeds, but then other times it's just not available. Also, the wifi indicator will show multiple bars (or waves?), indicating that there's a strong wifi signal, but the internet just won't work over it. This will happen while I'm sitting next to her with my AT&T iPhone 4, just sailing away on the internet with no problems at all. SO, we took her phone to our local Apple Store in Troy, Michigan for a Genius Bar appointment. The Apple Genius told me that he had the EXACT same problems with his new iPhone (true story or false, I have no idea), so he exchanged it for another one, and that also had the same problems. He thought there were a few things going on. First, he said the LTE issue is a local issue for us here in the Detroit area. AT&T just rolled out LTE here 2 weeks ago. So, they are having a number of bugs related to the network being new and possibly a little premature. He thinks the network will be better in the next few months, from what he's heard from AT&T. The wifi issue he believes is a software problem, unique to iOS 6 and its installation on the iPhone 5. Since the LTE thing keeps going on and off, and wifi keeps going on and off, the data connection on the phone is very unreliable at this point, and the phone is using a lot of power to try to maintain that connection, hence the faster battery drainage we're exeperiencing as well. The bottom line is that there was nothing he could do for me. He wouldn't even let me TRY a phone replacement to see if it would be better. His suggestion was for me to sit tight and wait for Apple software updates and for AT&T to improve their network. However, I am scheduled to have MY new BLACK 64 GB AT&T iPhone 5 delivered tomorrow on October 1st (I know, it sucks that my wife got hers 5 days before mine, when we ordered them at exactly the same time). I will restore it from my iPhone 4 backup on my iCloud (like I did with my wife's) and I will se how it goes. If that phone connects and works flawlessly while my wife's phone continues to have problems, then I will return her phone for a new one. On the other hand, if my phone behaves the same way as hers, then I guess I'll follow the Apple Genius' advice. So, what do you all think? Should I have been okay with the Genius' explanation, or should I have been more insistent on a replacement iPhone? I will post an update after I receive and set up my new phone tomorrow night. It's weird, but part of me actually WANTS it to have the same problems, because then I'll know it's systemic. If I don't have any problems, I'm going to have to convince the Apple Store to give me a replacement, IN SPITE OF the experience of one so-called "genius." I just don't know if hers is a lemon, or if there really is a problem going on with all of them.
