Almost a month ago, Apple released the i Phone 3.1 update. Once the i Phone 3.1 firmware update is done downloading it will start the installation process on your i Phone.
Today Apple has released the i Phone 3.1.2 update for i Phone and i Pod Touch users. An i Phone OS 3.1.2 software update window will show up, click on the Next button. If you are having trouble downloading the i Phone 3.1.2 firmware through the i Tunes Application then you can directly download the appropriate firmware for your device using the below links: Note: Don't use Safari to download i Phone 3.1.2 IPSW files, instead use another browser. ZIP and i Tunes is not able to recognize the firmware that way.
As such, we're seeing many reports of folks experiencing issues.
Truth is, some of it may just be down to Apple's servers being slammed right now, but there's other issues that you can help resolve yourself.
First make sure that your Apple i Pad will be compatible with new i OS 8 and then follow our next guiding steps to update i OS 8 from i OS 7 or below on i Pad. Remember to have a complete backup stored either via i Tunes or via i Cloud, in case you need to downgrade form i OS 8 to i OS 7.
