I can't update my iPhone on another computer

I have iPhone 4 running 4.3.3 and i'm trying to update to IOS5
my laptop has a low space in local disk C so i can't backup and update, so i installed itunes on another computer with larger local disk C and connected my iphone and authorized the computer as my 2nd of 5 allowed computers to authorize. but when i tried to update it said that only name, notes and calenders are going to be backup-ed and all the other data will be lost !
is there something wrong i did ?

Just because its authorized, doesn't mean that it has all of your media on it. That being said, when you upgrade to iOS 5, it uses all the data saved on the computer and settings for your sync to reinstall everything. If you have purchased stuff on your phone you can click File and then I believe Get Purchases or Transfer Purchases and it will back them up first and you will be able to reinstall those. But any ripped media that was not purchased through iTunes your out of luck.

I am going travelling - Can I update my I phone 4 using any computer as long as I log in to my itunes account??

Here's the deal: You can update iPhone software on any computer, as updating software does not touch any user data or settings...unless something goes wrong(rare). If something were to go wrong, and this is not the computer you normally sync with, you could lose ALL of your data. You also do not want to sync, if this is not the computer you normally sync with. So, make sure you disable auto-sync under iTunes>Preferences>Devices first. Do not sync after you update.

How can I update my iphone without a computer or itunes?

I was at the luandromat using my laptop to sync my Iphone 3gs and there was a large power surge. It fried my laptop and my Iphone 3gs. Now I'm using my old Iphone 3g whcih is running software 3.1.3 and I want to know how or if I can update the software with out having access to itunes or even a functioning computer.

"Really? "
Yes. It has always been this way. Itunes and a computer were listed as REQUIREMENTS on both the box the iphone came in and the website.
"If that's the case then I think I may just switch to the Droid network."
Enjoy your Droid.

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.

HT4972 my iphone is not installed sim card.so I can't update my iphone.

That's correct, without a supported SIM card you can't set up the phone.
If your carrier supports unlocking, you can use any SIM after your phone has been unlocked by the provider:

Follow these instructions to initiate the unlocking process for your iPhone:
Check if your carrier offers unlocking. Only your carrier can unlock your iPhone.
Contact your carrier and request an unlock.You may need to meet certain requirements to qualify for unlocking. After your carrier submits the unlocking request, it may take up to seven days.
Once you receive confirmation from your carrier that your iPhone unlock has been processed, proceed to the next section.
If you have a SIM card from a carrier that is different from your current carrier, and you've received confirmation from your current carrier that your iPhone is unlocked, follow these steps:
Eject your SIM card and insert the new SIM card.
Complete the setup process.
If you do not currently have another SIM card you can use, follow these steps to complete the process:
Back up your iPhone.
Erase your iPhone.
Complete the setup assistant and restore your backup.
Additional Information

Restore your iPhone.
Contact your carrier to verify that the unlock was applied in your carrier's system.

Updating iphone on another computer?

OK, long story. My recent wife and I both have iphones. The company she works for doesn't allow itunes on her company laptop which is her only computer. Therefore she can't get updates of new versions of itunes software on her iphone. I try to update her iphone on my computer, but a prompt comes up after I click on 'update' that says, if I continue she will lose all her songs, videos etc on her iphone. Can anyone tell me how I can update her iphone on my computer without losing all her purchased data?
Thank you

This will be a problem then.
In regards to iTunes content, an iPhone can be synced with a single computer only.
If she used her own iTunes account to purchase her iTunes content - not with your iTunes account, you need to create another computer login account for your wife. iTunes includes an option to transfer content that was purchased from the iTunes Store from an iPod or iPhone, but this is for content that was purchased from the iTunes Store only.
After getting her computer login account set up on your computer, she needs to authorize the computer with her iTunes account with iTunes. After doing so, with her iPhone connected and without syncing, at the iTunes menu bar go to File and select Transfer Purchases From- the name of her iPhone.
Even after doing this, when syncing iTunes content for the first time, the iTunes content on her iPhone will be erased followed by being replaced on her iPhone via the iTunes sync process. After this, she can install firmware updates on her iPhone and purchase iTunes content with her iTunes account when logged into her account on your computer.

Hello, Chryslers6.
Thank you for visiting Apple Support Communities.
I understand that you are wanting to update your iPhone 5c via the over-the-air option. You will need to be connected to power and a Wi-Fi source to use this option. You should be able to do this while being connected to any Wi-Fi network. You also have the option to update via iTunes. The article below will walk you through the process of updating your iPhone.
Update the iOS software on your iPhone, iPad, and iPod touch
Cheers,
