I can not update my iphone 4 to ios5? I get a error message saying that "the iphone could not be resotred, this device isn't elgiable for the requested build. If anyone ran into this problem please advise if you were able to fix this errror. Thanks
Thanks to a Apple tech support agent we were able to find out the problem. If anyone else runs into the same problem. These are the steps you should take to fix the problem becuase more then likely you have had a jailbroken device on the computer that your using to do the update.

-In TinyUmbrella unchecked the option that says "Set hosts to cydia on exit"
-Press Apply Changes

cant sync my iphone contacts with yahoo, it says "unknown error (4)" and tells me to come back later, been doing it for months. Any ideas on how to kill it?
Hey joshuafromisr,
If you resintall iTunes, it should fix the issue. The following document will go over how to remove iTunes fully and then reinstall. Depending on what version of Windows you're running you'll either follow the directions here:
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP

or here:
Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7

Can't update VZ iPhone 4 to iOS5
This is for my wife iphone on her own Windows 7 x32 system.
Verizon iPhone 4 running 4.2.8
Sync her phone, updated to iTunes 5, sync again, updated apps, sync again. I then choose to download the iOS 5 update only first.
I then tried to update the iPhone to iOS 5 about 5 times and each time it would get stuck on "iPhone backing up". Left it alone for about an hour and the progress bar was about 1%.
I once reset the phone and tried again nothing. Also moved the device to a different USB port and nothing.
So can't get the iPhone to update, any ideas?I have the same problem, i´ve tried several times to update, was you iphone jailbreaken aswell?

Updating my iPhone 4 to iOS5 I've got error (-402653077)
While updating my iPhone 4 to iOS I've got this error message:
An error occurred while backing up this iPhone (-402653077). Would you like to continue to update this iPhone?
What shall I do? Cancel the update and try again?
Please let me know,
AndreaOne more thing: My concern now is, if I choose cancel will the update abort and nothing will happen to my iPhone contents or will I incurr in some troubles/dataloss?
Does anybody has a clue? -

I can't update my iPhone 4s to ios5?
I recently just bought a iPhone 4s that is currently the 5.0 patch, but I cannot update it to 5.0.1 ? I downloaded the update but when I install it says that it's not compatible? I am currently on my iPhone and will be on my computer tomorrow to quote the exact error.
My iTunes is up to date
Windows 7
Thanks in advance,
Brian***ATTENTION EVERYONE!!!!!
Here are detailed step by step instructions, for these who are not exactly super tech savvy. :-)
Adjusting you DNS settings work like a charm!
Google Public DNS IP addresses
The Google Public DNS IP addresses (IPv4) are as follows:
8.8.8.8
8.8.4.4
So do this on your IOS iDevice:
-Go to settings,
-Then to Wi-Fi,
-(Find the network your connected to) touch the blue arrow all the way on the right of the Network WiFi Name,
-Go down to DNS (you will most likey see something like for example: 192.168.254.254, 192.168.1.1) in that field,
-Totally delete everything in that DNS field,
-Replace the pervious address with exactly this: 8.8.8.8, 8.8.4.4
-You are all done, just exit out.
Then just retry to check for updates and all will go smooth, the problem is - I think some ISP's have got certain Apple servers address blocked, or Apple's software servers are not registered correctly to point to the right physical location your IOS iDevice is trying to get the update from, when on certain ISP's networks. For one I am on Windstream, and it appears they have some kind of problem either blocking or not routing the IP correctly.
Thank you so much for the instructions
Worked like a charm, once again thank you.. -

Why should anyone help you if you cannot be bothered to clearly communicate the problem you are having?
This is a user to user forum, no one here is going to do a darn thing to fix your problem. That being said, we can offer suggestions on how to recitify the issue if you can be bothered to provide specifics of the problem. -
I would like to update the apps on my computer so somebody please help.
Go to the featured tab of the App Store and swipe down to the bottom. Tap on your Apple ID. Tap View Apple ID in the pop up window. Then enter your password. Go down to County/region in the next pop up window and change the store in there - if it doesn't change automatically for you via a message from iTunes.

How can I update my iPhone 3gs to iOS4, after iOS5 came out?
I am still running iOS 3 (1.3) on my iPhone 3GS and I'm happy with it - but all the new apps requires iOS4 and now I'm sick of this. I want iOS4 (and not iOS5, cause it will drain my battery as far as I've understood).
How can I update my iPhone 3GS in a normal way to iOS4, through iTunes or another easy way? I have never jailbreaked an iPhone so I don't know too much about "backdoors" into my iPhone.The only Firmware in the iOS 4 series that Apple is still signing for the iPhone 3GS is 4.1. So you could restore to 4.1. You will have to download the 4.1 IPSW from Apple, and then install it with iTunes, Option Click Mac or Shift Click Windoz, on the Restore Button and then select the 4.1 IPSW on your computer. The current iTunes may give meaningless Errors, I doubt because you are Upgrading. But if Error Message is given you will have to search the Web for ways to Exit Recovery.

i have just updated my iphone 4 to ios5. i cannot find my photos anywhere can you help? Thanks
Hey Kate
if you have backed up your iPhone, photos that were taken on the iPhone will be in the back up file. Any photos synced to your iPhone from a computer will need to be synced again. To restore your iPhone from a back up right click on the name of your iPhone in iTunes and select restore from back up. -
Since updating my iPhone 4 to iOS5, my music stats (play count, last played, etc.) no long sync to iTunes. How can I fix this? Thanks for the help.
If you have any podcasts in your iTunes library you should see a Podcasts sync setting tab to the right when you connect your phone and click on its name on the left sidebar (see image below). On this tab check to sync podcasts and sync your phone.
