Error on upgradation of iPhone 4 with 4.2.10 to iOS 5

Dear Jose,

I have read your question and I understand that you can’t upgrade your iPhone 4 to IOS 5.

You need to check the following steps:

• You need to have the latest version of ITunes.
• On ITunes  click on help then check for updates.
• Make sure that you are able to connect to the internet.
• Verify that your operating system is up to date.
• Check for automatic updates.
• If you have any other USB devices connected, you need to disconnect it.
• Make sure that your anti-virus and security software is up to date.
• You need to make sure that there is available space on your device for the update.
• Remove any kind of software on your IPhone that might be taking space, that you don’t need it.
• Make sure that you have backed up your iPhone because restore will erase everything.
• Restart your computer and try again.
• Sometimes you need to do several trials and it will work.
• If you need to restore your device.
• Connect your device to your computer.
• Select your iPhone then click restore and update.
