iPhone 3GS iOS 4: Are You Experiencing AT&T Loss of Data?

The new Apple iPhone iOS 4 software update has had a few small ups and downs and the latest complaints is about the AT&T unlimited data plan.

We found via TiPB some news about a customer who has the Apple iPhone 3GS; he updated his smartphone with the new iOS4 software update on his AT&T iPhone and experienced problems with data connection.

After the much anticipated software update of the year for Apple iPhone fans he could not even make calls after downloading the update, after contacting AT&T after this problem he was told that there have been some isolated incidents of Apple iPhone 3GS with iOS 4 where unlimited data plans cannot connect to the network.

Apparently Apple is working on a fix right now, Apple did however put his name on the contact list so they can notify him when the issue has been resolved.

We would love to hear from AT&T Apple iPhone 3GS owners who have downloaded the new iOS 4 update who is having the same problem, please let us know in the comments area provided below. Thanks

    I am a 3gs owner who has just recently updated to ios4. I can make and receive calls, and the phone appears to be connected to the 3g network (from the full bars and little 3g symbol in the upper left-hand corner of the screen) but will not actually do anything that requires use of the data plan (i.e. will not load anything in safari or mail). When I try to open a page in safari, I get a little pop up with an error message saying "server has stopped responding"

      Well, it's good to know I'm not alone…

      You'd think with all the freaky Apple paranoia, they'd at least make decently working products, what with the iPhone 4 antenna thing and then this

    Since I updated my iPhone with the iOS4 system I have been receiving the “unable to connect to iTunes” error message in the app store and iTunes (mobile). It does seem to be more of an issue when NOT connected to wifi, but I still do receive the same error on occasion either way. It’s quite frustrating. Sometimes I can view the apps or songs, but when I go to view them by selecting them separately, I get the error message.

    I updated my 3GS yesterday and had data for a couple hours, then it completely went out. I can still make calls, but I can't surf the web and most of my apps do not work since they require an internet connection.

    1. I updated to ios 4 and now I can not connect to the internet. Stayed on the phone with AT&T for two hours with no results. I am on a business trip and can not receive emails on my phone.

  6. I have the same exact problem. I can only make phone calls and send basic text messages. However, I cannot play any games that use data, or send emails, or browse the web at all. Its extremely inconvenient, and I didn't even bother calling AT&T as I knew it was due to the update. I just wonder how long until it should be fixed.

    same complaint! Can not send multimedia messages anymore, but I am paying a monthly fee for it. Being a loyal customer since 1993, I feel we should have been made aware of the issue before hand. Not a happy customer right now. Seeing as 90% of my job is done by using my phone and my old options.

    When I update to Ios 4 my phone has been very sketchy on the service end. Sometimes my phone wont even ring and I will receive voicemails hours after they were left. And on top of that I was having issues restoring my phone from backup. The phone kept popping up with an error in itunes and eventually ended up saving over my most current restore. I lost all my contacts and such from the last 6 months.

    I have an iphone4 with the grandfathered data plan, and I've been having frustrating issues with my data connection cutting out since I got the phone.

    I'm considering returning it and sticking with my Nexus One. I've been nothing but unhappy with this phone since the day it arrived.

    If you're experiencing an issue where the iPhone refuses to access network data (Web pages [Safari reports "Safari can't open the page because it can't find the server."], email, Google Maps data, etc.), the fix may be drop-dead simple:
    Tap Settings
    Tap General
    Tap Reset
    Tap Reset Network Settings
    This will cause your iPhone to restart, and will delete any stored Wi-Fi passwords as well as DNS settings and more. It may, however, restore your ability to join a stubborn wireless network, let you access stalled Web pages, or eliminate issues with EDGE data access that can occur for various reasons.

    After upgrading my 6 month old 3GS, the cellular functions work fine, I can make and receive phone calls and connect via 3G. WiFi will not connect, or in the few instances it does it drops after a few seconds. I have switched off the WiFi for now and am living on 3G; but as one person mentioned this means that ATT is going to have a lot more traffic on their network.

    I have also experienced problems after upgrading to OS 4 on my 3Gs. I downloaded to OS 4 last week and just today cannot connect to the internet. I have also had some spotty email problems such as not being able to send etc… Another issue is the significant battery drains. i can almost watch the percentage drop. Just this morning I went from 100% to 57% from 8:00 to 11:20am. Hhmmmm, not impressed so far…

    if you go into settings and change from the 3g network to off and turn on the edge network it will work that is what i had to do and i got all my messages .. it will be slower then 3g but it works on the edge network still so its a fix until they solve the problem

    To Chris –
    AT&T had me do that on the phone a week ago. It worked, but the next day, it did not. Sorry, it's not a fix.

    Same problems in US Columbus Ohio. iphone 4 1st phone never connected out of the box purchased at ATT store . returned to apple store and they replaced it 2nd iP4 worked fine for about 12 hours then lost cell data. just get spinning wheel. I also have unlimited data plan. My phone was an upgrade from a 3gs that had OS$ installed and I didnt notice any data problens but had only upgraded for about 12 hours before switching. for what its worth 3gs was still turned on whhen they switched the number to the IP$ and they at some point switched me to enterprise data plan by mistake and was then switched back to regular unlimited data plan.. dont know the sequense of events with the switch to enterprise data and back butATT support had to do a "manual override" to get me to the unlimited plan. Maybe on overnight backup at ATT the "Manual Override"s are being canceled leaving us with no data plans? new posters on this thread please post your data plan Does this affect anyone othe than people with unlimited plans?

    3gs doesn't hardly function as a reliable phone anymore cuz of my ios4. have difficulty sending texts. must hit-rend 5x for it finally to go through. it was working great before. has had no accidents or damage. is in encased safely and is relatively new. the only variable change was ios4. its amazing how patient i am with this issue though, cuz i strongly support apple. in any case, i sure hope they fix it soon.

    I cannot use3G on my 3gs after I updated to iOS4. I spoke to ATT for an hour and we reset and did tests. Finally they told me to switch back to edge only (3G off) for the time being. That works BUT… They called me back three days later after reviewing my case and tell me now to contact APPLE.

    I did the same. I have an international data plan with an international provider who has a data agreement with AT&T. Everything worked fine until I upgraded when all internet connectivity failed. Is anyone at AT&T or Apple reading these comments and doing anything about this?

    I installed the 4.0 update this morning and after the update I lost ALL of my data! I was able to restore my Apps but now cannot access them. They are on the screen but as soon as I press on them, they go back to the original iPhone screen.

    AT&T and Apple reps told me that many people are experiencing a similar problem. I am furious that I cannot get my contacts back!

    Nothing new to add to the problem fellow iPhone users. Have 3GS and uploaded iso4 software. 3G icon is showing full strength but not access to anything data related, unless I am on WiFi.

    FYI Mike: back up your contacts with the Sync On The Go app from iTunes, it’s free and easy.

    E & 3G seem rather slow.
    Also – at same location in my house I will see 5 bars and 3G, try to use it and the bars drop to <5. Within minutes it may revert to E.
    Seems like even the new iOS is not accurately reporting the signal strength.
    I have plastic case so I am not touching the antenna
    Any thoughts? Bob

    I upgraded my 3gs to iOS4 and lost all data connectivity to the cellular data network. My WiFi connection still works fine. Think I'll go into the Apple Store and make sure they know that I'm affected, in case there's any remuneration later.

    I just upgraded to 4 and lost about 95% of my contacts. I am sick. This was the first time I had ever connected my phone to iTunes, so I hadn't yet had the opportunity to back up my data. I can't believe I don't have access to phone numbers that I will never, ever remember.

    Same here. Last night i upgraded to iOS 4 on my 3GS and now 3G data connection has stopped working. The browser doesn't open any pages etc.

  44. i have iphone 3GS. downloaded software upgrade 4.02 with new carrier settings. started getting problems with signal. restarting the phone restores the signal temporarily, and after about ten minutes its 'No Service' – no 02 connectivity or 3G connectivity. I thought 4.1 may fix the problem, but seem to have made it worse, restarting the phone no longer restores signal. this is ridiculous. eagerly awaiting a fix.

    Same problem. No 3G data. Can make calls fine. I turned off 3G and can use edge at slow speeds. Odd note, 3G works in the morning but not during the day and night ! Used to be able to use the airplane mode to reset and get a few minutes of 3G at night but now that doesn’t work anymore. Could it be some weird problem with an app I downloaded? I have so many.

    Same here… Been happening for awhile now, but I thought it was just me! I have iPhone 3GS and ever since I reluctantly upgraded to iOS 4 my 3G signal disappears without any rhyme or reason. Usually, if I switch to WiFi I can reestablish a connection but not always. It lasts anywhere from minutes to hours. Now iTunes keeps prompting me to upgrade to iOS 5, but after my experience with iOS 4 I’m afraid of anymore possible complications, so I’ve yet to update my phone. So far I’ve only heard bad from 3GS owners who’ve updated to iOS 5. Anyone have any suggestions or possible solutions? Thank you to everyone who shares my pain and frustration… Hopefully, it will be alleviated soon… Once AT&T gets enough complaints!
