Problems updating to 4 01
The first -- and simplest -- method is to just do a direct update.
You can do this by clicking on the update button on the device's information page in i Tunes, or just simply by letting i Tunes continue with an upgrade when it automatically detects that new software is available. Many users can easily be intimidated by this method, as at first glance, it infers that one might lose their settings or media if they restore their i Pod, rather than updating it.
This is because rather than just attempting to update only the changed parts of the i OS software (as an update would do), i Tunes completely erases the device, installing a 'clean' operating system, and then it restores your various settings and syncs your apps and music back to your i Pod or i Phone.Always update your PS4™ system to the latest version of the system software.By updating, you can enjoy additional features, improved usability, and enhanced security.Because apparently, the i Phone 3G needs to be restored, rather than updated, for things to work properly.We aren't sure why, but what we do know is that in order to get i OS 4 onto your i Phone 3G, you must do a restore (not an upgrade).
