How to Upgrade iPhone 3G to iPhone 3.0 Firmware


My doctor-friend who owns an iPhone 3G asked this morning how to upgrade his iPhone OS to iPhone 3.0 firmware after reading my post on iPhone 3.0 firmware (OS) Update for the iPhone 3G, which is coming out next week. My friend has not done any update on his iPhone 3G OS yet as of this writing so he’s left uncertain about the steps in updating his iPhone 3G firmware to v3.0.

For those with the same concern, here are the simple steps that Apple provided if you are going to upgrade your iPhone 3G to iPhone 3.0 firmware. You can, by the way, update your iPhone 3.0 firmware via iTunes 8.1 and follows these steps:

  • Connect your iPhone to your computer.
  • When iTunes opens, select your iPhone under Devices in the Source List on the left.
  • In the iPhone Summary pane, click Check for Update.
  • Click Download and Install. Do not disconnect your iPhone until the update has finished (the graphical version of this tutorial is shown below. Click on image to enlarge)

Steps in the iPhone 3G Update to iPhone 3.0 Firmware

I hope this simple tutorial will help everyone looking for info on how to update iPhone 3G OS to iPhone 3.0 firmware. The steps are quite simple really. You just need to know iTunes a bit more to get around this procedure.

However, just a few simple notes. The above steps worked in the last iPhone 3G 2.2.1 update (which also worked with iPod Touch). In dealing with the new iPhone OS 3, we are not really sure if this procedure will work. There are a few things under consideration. Will Apple sell new handsets (hardware) for the iPhone 3.0 firmware to work? Will it support both iPhone 3G and 2G? Will iPhone OS 3 update be free?

Honestly, we are still in the gray area around here. We have not really been very conscious about iPhone firmware upgrades ourselves and we still lack vital info on this subject. We are simply hoping here that the previous steps in doing an iPhone 3G firmware update holds true for the iPhone 3.0 (OS 3) firmware. Of course, we are also hoping the firmware update to be free (as usual) without the need to buy a new iPhone unit/handset :-)

    So what if you have the first iPhone that came out? the non 3G one (I guess it’s called the first Gen iPhone or is that the 2G one that has been mentioned ) will the 3.0 update work on that phone?

  19. Barbara says:

    Is there a way to plug the iphone into a laptop and have the laptop use the 3g network the phone uses?

  20. Susan says:

    This is how you upgrade to iphone OS 3.0 . You need to download the .ipsw file and then shift click on update or preferably restore.

    Then use unofficial quickpwn to fake the activation process. Otherwise you would need a dEV LICENCSE

    To downgrade stick it in DFU mode and shift click restore > 2.2.1

  21. JayRay says:

    Yes the update is free for iPhone users both 2G and 3G. But for iPod Touch it’s $9.95 I believe.
