If you are an iPhone user then you will probably be aware that a new version of the iOS (iPhone Operating System) is available for your iPhone. The new version 4.1 iOS will fix a faulty proximity sensor, adds ‘HDR’ photo capture, improves iPhone 3G performance, plus a new social Networking style “Game Center” is added – plus some other updates. The Game Center, allows users to play social gaming on your iPhone, playing multiplayer games against online opponents. HDR photography is something which was only in the realm of DSLR cameras but now on the iPhone you can take photos which capture a wider spectrum of light ranges using the new high dynamic range (HDR) setting on iPhone 4.1 OS. HDR photos automatically combines multiple exposures into a single HDR image (one underexposed, one over exposed and one normal exposure).

Before upgrading to iOS 4.1 you should follow these steps;

Step 1 : Make sure you are using the latest version of iTunes – Currently iTunes 10. Now connect your iPhone to your computer via the official iPhone USB Cables.

Step 2 : When iTunes opens, select your iPhone under Devices in the Source List on the left. e.g. “Shanes iPhone”

Step 3 : In the iPhone Summary pane, click the “Check for Update” button.

Step 4 : Click “Download and Install”. Do NOT disconnect your iPhone until the update has finished.

iTunes : Unknown Error (13)

iTunes Unknown Error (13)
Some people are getting “Unknown Error (13)” problems when updating to the latest iOS, with errors appearing in iTunes saying the iPhone could not be restored or updated and reporting that “An unknown error occurred (13)”.

If this happens to you then you probably …

(a) did not have the correct version of iTunes setup before installing the latest iOS upgrade.
– It should be version 10 or the latest version as per the apple website

(b) You did not have enough disk space for the software to be extracted or for the backup to be saved.

If this happens you can try restoring your phone but you will probably lose everything and you will have to do an iPhone Restore using your last backup. This will reset the iPhone to the factory Settings.

When this happened to me (because I had version 9.2 of iTunes and tried updating) – I connected the iPhone to a different PC and this solved the problem. I then re-synched the iPhone on the original PC and restored the iPhone via the last valid Backup which luckily was that evening prior to trying the iOS 4.1 update.

WARNING : Please be aware of the risks when following on-line instructions from any websites.
This post was added because the “Unknown Error 13” occurred to me and the solution to fix the issue took a few hours for me to find – so hopefully this will help people in similar situations, getting Error (13) or hto elp those who didn’t know about updating iTunes to version 10 (or the last released version) prior to attempting iOS updates.

If in doubt ask an experts opinion as each PC / iPhone setup may differ. Some people may have good backups some may not and failure to follow correct Apple instructions could result in you losing data so please visit for all the details on the latest software updates for your iPhone.
