Problem updating iphone 3gs to 4 3
It seems as though many folks running the i Phone 3G are getting ‘3002’ errors when attempting the update. With my trusty old i Phone 3G in hand, I set off to install i OS 4 goodness. Once in and i Tunes finishes backing-up and syncing, if you are not greeted with an update alert, hit the ‘check for updates’ button.
To avoid this, it was suggested one restore their i Phone 3G first. You should be greeted with a notice that i OS 4 is available. Before you install you’re going to want to ‘restore’ your device.
If you’re concerned about ‘restoring’ your i Phone, you shouldn’t be.
As long as you’ve backed up your device, a restore and update will do nothing more than wipe your device clean, install the new OS, and then slap your backup right back down on your device.
To make things even easier, if you’ve already been greeted with the i OS 4 update option (you should have seen this when you checked for updates), when you click the ‘restore’ button you should notice a ‘Restore and Update’ button.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).
