    Just came back after spending an hour at the Apple store with a genius. He couldn't do much except run a diagnostic scan and reseat the sim card. Miraculously, I have much better 3G service in my office now! The phone shows 4 bars instead of 5 but so far it's been consistent.

    Folks using Android phones are having data problems as well:

    Looks like an AT&T issue

    If it is a network issue, I don't understand why it doesn't seem to be affecting 3G/3GS phones. Just tried loading some pages on my i4 and my co-worker's 3GS at the same time. No issues on the 3GS, but my i4 kept timing out.

    This is definitely not related to the antenna issue. I believe this is about AT&T's network not being able to keep up. About a week before I got my iPhone 4 my 3GS basically lost all data connection over 3G. Now on my iPhone 4 I'm averaging around 400k on 3G. I went to the AT&T store to complain today and I was more knowledgeable than anyone there. Nevertheless the lady that was helping me out was very nice so I can't complain too much. I ran speed tests on my phone, their display iPhone 4s, a 3GS they had on display, and the AT&T lady's own 3GS, and they were all getting spotty performance. So this is definitely a network issue rather than a hardware issue. Although I suppose it could be a problem with iOS 4 also. Their suggestion was that we stop using our iPhones so much to free up their network. I guess it makes about as much sense as Apple telling us not to hold the phone with our left hand.

    No offense, but we "don't understand" because none of us have any remote clue about how data is transferred over a cell connection. It's frick'n magic to us.

    It could very well be a combination of tons of network activity communicating different from the older version phones, or sun burst radiation, or military lockdown frequencies, or Santa Claus, etc...

    What is lame is that AT&T and Apple are being so quiet about it. I did call AT&T who said I have an outage in my area, but couldn't elaborate further. The phone rep did assure me it wasn't a hardware issue with the phone... since I'm sure a $12/hr phone rep knows all about how the iPhone works...

    Best advice I have - if you have the phone because you really want it, keep it and stay optimistic that, given some time, they'll sort it out. If you have the phone and are super pi$$ed, return it and pick a different phone.

    Maybe iP4 3G data runs on a separate "channel" which is broken/overloaded on some towers.

    I called Apple and they gave me these tips if your Safari or other programs are running slow.

    FIRST TIP

    1. Go to Settings
    2. General
    3. Go to the very bottom and touch "Reset"
    4. Touch "Reset Network Setting"


    SECOND TIP

    1. Go to Settings
    2. General
    3. Network
    4. Turn Enable 3G off, wait a bit then turn it back on.


    THIRD TIP

    1. Take a small paperclip and insert it in the hole on the right side of your phone to eject your SIM card, wait a bit, push the card back in.


    I tried all three of these and now all the websites that were not loading are.

    I ran into a problem yesterday where I had full 3G bars but could not connect to the data network at all. I just went in and toggled airplane mode on and off and the phone searched for the connection again and then I could connect. I don't think this is related to the antenna issue but is something going on at the network layer. I remember years ago when I used to use dial up internet access that there would be times I would get a modem connection but the ISPs IP server ran out of addresses and I couldn't connect to the network. The behavior I saw yesterday reminded me of that issue and there may be something similar going on that has to do with the network connection and not the wireless connection.

    Speaking of the antenna issue, I also noticed that when I cradle the phone and start seeing the bars disappear that when I toggle airplane mode, that the phone searches for a new connection and comes back with full bars and stays there as I contine to hold it cradled. My speedtest numbers also come back up too. This leads me to believe that firmware has to be at least part of the problem. Anandtech has confirmed that there is physical attenuation when you touch the antenna but they also said that in spite of that they were able to hold calls that they couldn't on their older iphones. It may be that when the firmware gets straightened out that we won't see many issues with connectivity in spite of whatever attenuation is happening because of touching the antenna.

    I'm in MD and got my Phone on June 29. I'm having the same issues with sporatic speeds. When they are good, they are great, when they aren't...they just aren't there at all.

    I just tried all three of your steps and did a speed test: results, sitting on my desk-- 43 kbps down, 0 kbps up.

    My problems started just after lunch on 6/30. I'm dying for a fix since I do not have wifi access for most of my day!!!

    PLEASE ATT and APPLE!!!

    I just switched to AT&T / iPhone4 yesterday from Sprint. Although I really like the phone it's painfully slow compared to my Sprint phone. The network has to be overloaded, it just has to be. In no way would this phone of this stature be like this out of the box. I'm also experiencing dropped calls, especially with other AT&T customers. Very fustrating.

    I am having 3G data problems in Parkersburg WV, specifically the downtown tower. It will show 5 full 3G bars out in the middle of the parking lot or in a building and the 3G data is either VERY SLOW or says cannot connect. Edge is way faster, at least 20 times faster. We both have the new iphone 4, and 3gs users I talk to are having no problems. What is strange is it is only the one tower/location, every other place we go it works perfect. I had a ticket in and they looked at the tower and said it was fine, and they went ahead and reset it anyways and we are still having the problem. Apple says it is not an issue with the phone since it works on every other tower, and AT&T says its not their problem because they show nothing wrong and other non-iphone 4 owners have no problem. Any thoughts? I have tried the SIM, hard restart, turning off wifi and blu-tooth, having AT&T re-establish my iphone to their system and last but not least restoring the iphone to factory. If anyone gets anything to work please post.

    I am literally having the SAME exact problems that you are talking about. It is truly the most frustrating thing.

    I am having dropped calls, people suddenly not hearing me through the phone and then it suddenly picks up again (and will do this on and off throughout a conversation). When it is not dropping calls on its own I also have the weird sensor mute/hold buttons turning on during phone convos. It will ring forever without a ringtone and I have to hang up try again. Internets being slow/not loading with all bars. It makes no sense. I had a 3GS and never ever had any of these issues, it worked perfectly, I would only expect the same and more from the iPhone 4.

    Apple please do something about this!

    No offense taken, but I don't think we need to understand the technical details of how 3G works. The bottom line is, 3G is a standard. The iPhone 4 shouldn't be any different from any other phone on AT&T's network. There's really only a few possible explanations for the issue:

    A. AT&T's network is having trouble.
    B. The iPhone 4 has a software problem causing this issue.
    C. The iPhone 4 has a hardware problem causing this issue.

    A could very well be true, but it can't be the only explanation. Otherwise other phones should be in the same boat, which is not the case in the admittedly limited testing I've done so far.
    B doesn't seem likely, since there are only 12 pages in this thread. If it were strictly a software issue, it should theoretically be affecting everyone with the iPhone 4 and at the very least, a lot more people than we're seeing here. We'd be hearing about this from blogs, news outlets, etc.
    C seems to be the most logical explanation. Units made at a specific factory, or in a particular batch would explain why it's not affecting everyone.
    I guess it could also be a software issue that's a result of manufacturing, so a little bit of B and C.

    Anyway, those are my hypotheses. I'm not the smartest guy in the world, but they make logical sense to me.

    As far as my testing goes, I've tried many of the things people have mentioned here and elsewhere, along with the things AT&T or Apple have suggested to people.
    - Wiping the phone and setting up as new didn't fix it.
    - Re-seating the SIM didn't fix it.
    - Covering the edge of the SIM contacts with tape to prevent the SIM from touching the metal tray didn't fix it.
    - Resetting Network Settings didn't fix it.

    I guess my next step will be to hit up an Apple store and see what they say.

    Shucks, I was actually optimistic that these would work. Maybe it's my phone, then, because it made it worse. I used to hit around 300+ kbps at one point. Now, with four tests, I can't even reach 80 kbps download.

    Loading www.apple.com/support website on my safari takes forever.
