Connect iPhone to iTunesSince the release of iOS 4 yesterday, many people who updated to the latest firmware are reporting various issues, including:

  • no cellular data (3G or Edge)
  • contacts disappearing
  • no push notification
  • MMS not working
  • photos turning out blurry

I have myself encountered my share of issues while setting up Google Sync for iPhone. The setup itself was fine but it took forever to sync my contacts and calendars. Later on, it came to my attention that it could have been Google’s issue and not iOS 4’s.

So what can you do if you encounter the kind of issues mentioned above?

A reboot is always the first thing to do but I doubt it’s going to fix anything. The second thing to do it to go to Settings  > General > Reset > Reset Network Settings. This usually fixes cellular data issues.

Now if you’re still experiencing issues, you might have to go for a more drastic fix: restoring your iPhone to a fresh state as opposed to a backup. This is your best bet. Sure you will have to start from scratch but your iPhone operating system will be as clean as if it just got off the box.

Did you encounter any problem after updating to iOS 4? What were they? How did you fix them?

    Hey K, try putting your iPhone in DFU mode, then connect it.

    I had the same issue regarding lose of my data coverage when upgrading my 3GS, but I found a fix without restoring my phone and losing all my apps and contacts, try this: Step 1. while connected to “Wifi” on iphone go on this website “Unlockit.co.nz”
    Step 2. Click custom APN
    Step 3. Choose carrier
    Step 4. Click create a profile and install
    After that your phone will reboot and you should be fine, hope it works guys, this has had to be my worst update experience by far!!!!

  • Sam

    After updating my battery depletes rather quickly, my phone get very hot

  • bakachin

  • Rikyt

    I went to http://www.unlockit.co.nz/ and it worked fine for me! Great Sean!

  • Solve it

    Hi everyone…i have the same problem where i couldn’t have internet connection on my iPhone 3GS…but worry no more!!!

    I restore my iPhone using the iTunes after that, not the restore to new phone, but restore from your backup..Backup you iPhone first!!! Have a try and good luck.

    What i’ve lost and need to sync:
    – everything (music, apps, video, picture i upload but picture in camera roll is safe, etc)
    (but not to worry u just need to sync back your iPhone and everything will be back as previous, so make sure you sync your iPhone with iTunes first before you restore!)

    what it solve:
    1. My Internet (edge and 3g)
    2. MMS

    At least its all about the internet were solved though.

    iPhone 3GS. Updated to ios4. I coudnt mms or use 3G data. I fixed that with deleting a file in a backup. So I got my Internet and voicemail back. Now the actual buttons to click to mms pictures are missing. Also can’t receive mms now even though AT&T says it’s activated.

  • k

    Hi all, thanks for your help, but the problem persists. Are there other ways? I kept trying the DFU mode method, but ended with the same problem.

  • syd

    ok, i installed iOS$ on my 3GS when it first came out. then i realized the problemsw above. i cant send any picture mail, or MMS, i cant have any internetreception. which sucks! instead of showing the little 3 lined, reception, bar thingy for internet, it just says 3G and im starting to get extremely tired of it. my 400 dollar ohone that i just got 2 months ago dsnt even have internet! ive done all the trouble shooting, the rep. cancled my signal from the tower, everything. still nuthing! and then when my mom upgraded her phone much the same as i did, al of her contacts dissapeared. this is just very frustrating! doesnt Apple do checks for these types of things instead of offering it to millions of consumers and letting them all have to deal with so many problems that could have been avoided if they would have left good enough alone? come on now.

  • tkdgirlms

    I updated to ios 4 and am not happy about it. First, during the update it forced me to do a factory restore due to some problem. Now, all my apps randomly close on their own and it won’t connect to wifi! What’s up Apple??

  • Rajesh

    Hi friends,

    I referred above all instruction & comments & tried upgrading my Apple iPhone 3G 16GB to IOS4, it was ulocked & Airtel simcard was used… I started at around 10 PM & waited until 12 in the midnight, but the process was still going on, hence went to sleep thinking before morning, it would have completed..
    In the morning at around 6AM when I woke up & checked my iphone, the phone looks like locked,.. on the phone it shows for the network ‘No service’ & ‘Emergency call’ only… I closed itunes, restarted the iphone twice but still the problem persist… Is the phone locked? Please help.

    Thanks & Regds,
    Rajesh

  • Justin

    My iphone 3g s downloads the ios 4.0 but doesnt install, it says the iphone cannot be updated because the firmware file was corrupt. WTF

  • Matt

    Isn’t this stupid… They post ALL over the internet how Jailbreaking your iPhone is bad, and screws up the software and what not… But as soon as I get back onto Apple software… BAM! INSTANT F!@# UP!

  • Matt

    Oh, I’ve restored my phone twice, back up and all. I’ve tried resetting to network settings like everyone says, I checked that discussion board, and I don’t get the little pop up thing that asks about the carrier.. I don’t know what to do.. I’m tempted to call Apple and ask… But I sense a giant waste of time in my future…

  • Solve it

    @Matt have u try UNLOCKIT.CO.NZ?

    I am very unhappy with the new IOS 4. I lost all my contacts, my photos, my music, and all my apps. On top of that, I had to reactivate my phone because it said that my SIM was not activate. I do not like this. Apple needs to fix it.

  • I upgraded my own windows based 3g iphone to 4.0 and it took a total of 12 hours…

    The only way I could get it to work was to backup first and then update, took forever but it did the business in the end…..

    Now my wifes macbook based 3g iphone upgrade to 4.0 was FAST (>1 hour) however it lost the carrier after the update and pin settings + wifi setting. So basically there was no cell network, reboot and resetting network failed to work, however flicking onto flight mode a few times and connecting to a wifi network did..

  • hothot

    Good news, now you can jailbreak your ios 4 phone.
    Just type jailbreakme.com on your Safari webrowser and follow the instruction. It’s that easy:

    JailbreakMe works on the device itself! Visit this website on your iPhone, iPod touch, or iPad to get started.

  • Ray

    Hi can someone tell me what to do when i update to the 4.0 the update freezes when it comes to updating mail accounts…i dont understand as i resarted it 3 times and still gets frozen at that point.

  • Steve

    I upgraded a 3G to OS 4.1. Was able to restore apps but lost all contacts, notes, pics, and calendar. Can’t believe losing the contacts! Almost wish I had my old Razr. Apple sucks.
