HT4972 Problem trying to upgrade iphone 3GS.

Why do I receive this message when I try to update my iphone 3GS?
"An error occurred when backing up this iphone. {-37} Would you like to continue to update this iphone? Continuing will result in the loss of all contents on this iphone."
Have the latest version of Itunes installed
Uninstalled 3rd party firewall. Unplugged all devices from USB except mouse and keyboard.
Temporarily disabled Antivirus program.
Added apple websites to trusted sites, including
Ran Diagnostics - Passed all steps
Checked hosts file - not blocking itunes from communicating with the update server
Verified Ports 80 and 443 are not blocked
What else can I try?
Thanks,
Gail

Well I spoke too soon.
The update was successful, but now I cannot connect to the 3GS data network.
Cannot get email and cannot open a page in Safari.
+"Safari could not open the page because the server stopped responding."+
+"Cannot Get Mail+
+THe mail server is not responding. Verify that you have entered the correct account info in Mail settings."+
Email and internet work fine on WiFi.........no data using 3GS network.
Looks like I will have to revert back to old OS.

I have a 2005 Jaguar xj8. When I tried to upgrade my 3gs to a 4g I got a ticking noise in the speaker and no one on the other end could hear me. I had to go back to a 3gs. My phone is shot and I need to upgrade. Has there been a fix to the problem?

My phone is shot and I need to upgrade. Has there been a fix to the problem? Apple told me there was some sort of interference with the airbag system. Jaguar was totally unhelpful.

Just upgraded iPhone 3GS to IOS5. Now there's 21GB of Others. How to get rid of it? It's taken up all the space on the phone.

Just upgraded iPhone 3GS to IOS5. Now in itunes I can see there's 21GB of Others. I have no idea what is that. I didnt have that before the upgrade. How to get rid of it? It's taken up all the space on the phone.

I posted a fix for this temporary issue earlier but here it is in short:
The memory "hog" that is "others" seems to be the OS as it's installing. It seems to want more than 12GB and you may get stuck at the point where iTunes tries to load everything back on and the iPhone has run out of space. What you need to to is un-check the "sync" box at the apps, music, podcasts and other sections, then click the button to sync iTunes with iPhone. This will result in iTunes deleting all the data it restored, but you'll put it back later. Once you caused the deletion of most of the data, iOS5 will resume installing and then "magically" shrink to less than 1GB. Then you can place check marks back in the boxes and re-sync all your apps and other data. You will have plenty or memory left.
I followed the above procedure and my iPhone works perfectly.
Hope this helps.

Upgrading iPhone 3Gs OS 4

How to Upgrading iPhone 3Gs currently version to OS 4?

Thank you very much, wjosten
This was the one straight forward clear answer I have been searching for a while now.
I suppose that you have tried this and know by experience that it works. It seems that you know what you´re talking about anyway. And I was assuming that it should work the way you describe, even though it doesn´t say clearly anywere.
And if I´m not mistaking, if I loose my contact info, I could always sync it back through MobileMe, right?
Thanks again. Looking forward to the update:)

Problems trying to upgrade from Solaris 10 update 4 to update 8

Hello,
I am having problems trying to upgrade a system from update 4 to update 8. I have broken all the mirrors and everything is now setup off of one disk, yet I do not get the upgrade option when I boot from the CDROM. Anybody have any ideas?
It is a pretty basic system and I do not understand why it will not let me upgrade.
Thanks for your help,
Gary

If you boot your system from the CD-Rom, you can test its upgradability by performing the following steps:
create a file named for example /tmp/pf_profile, which contains:
install_type upgrade
root_device /dev/dsk/<your root slice>The run the pfinstall program on it:
/usr/sbin/install.d/pfinstall -D /tmp/pf_profile
.. with a bit of luck that should validate your installation and report any potential problems which might cause this.
Also, have you had a look on the following thread?

simply try doing a back up and restore
when going thru the activation screen, select SET UP AS NEW and then test your device. if it is not shutting down then it could be 1 or more apps tht have been downloaded wch could be affecting the device
you will then need to follow the process of eleimnation, meaning add 2 apps and then monitor your phone, if nothing happes then add another couple of them and then check
good luck !!

After downlaoding ios5 and installing I get the message "we are unable to complete your activation at this time" when trying to update iphone 3gs to ios5 using itunes. Can anyone help?

Hi David,
any luck later?
I'm experiencing the same issue and I see that you're also posting from China. Not sure is location-related but if you managed to activate you iPhone: how did you do it? Just keep on trying?
I'm a bit fed up of trying. It's already two full days...
Thanks, ciao.

Activation issues are almost always the result of a device that has been hacked or jailbroken.
