How to upgrade iPhone OS to Version 3.0.1?

Upgrade your iPhone Operating System to Version 3.0.1.

If you are still running iPhone OS 3.0 your iPhone could be hacked with a simple SMS message. That was the news yesterday.

Apple quickly rushed to fix this issue and released a patch OS upgrade version 3.0.1 which does nothing but fixes the SMS Vulnerability.

It would be a good idea, just to be on the safer side, to upgrade your iPhone OS from version 3.0 to version 3.0.1. It’s not complicated, just follow these simple steps.

Connect your iPhone to your computer and launch iTunes. Once on iTunes choose your iPhone device to get to the Summary page where you can see some details about your iPhone. You should be able to see the software version being 3.0.

Once your iPhone restarts, if you go into the iTunes iPhone Summary tab again you should be able to see the Software Version number 3.0.1.

It’s just that simple to upgrade your iPhone OS from version 3.0 to 3.0.1. In fact this would almost be the case if you upgrade to any other version as well.

I hope you find this information useful. If you have any questions or comments please let me know in comments.

    hi, I have the iphone 3g , not the 3gs ,is it true that if we upgrade to the version 3.0.1 we will not be able to jailbreak it anymore ? I have heard a rumor that they made it impossible to do so with that upgrade . is that true ?

  3. jake

    you can definutely jailbreak and unlock 3.0.1
    however i cant update to 3.0.1 like it explains above anymore because itunes only offers 3.1 (which cant be unlocked so i dont want to do) is there anyway at al i can upgrade to 3.0.1 when itunes only offer 3,1???? thanks

    @jake – I'm not positive that you can get around the iTunes way. Anyone have any input to this? Please share.

    Jayson – I think you still can jailbreak your iPhone with the 3.0.1 firmware. I'm not aware of any restrictions. Correct me if you find out otherwise. Good luck!

    I have a new 3GS (new from the box, not connected yet) and I'm don't know what version it is. how can I know the version without risking the device (I need to know if I can jailbreak it or if I have to wait for the Dev team to come with a 3.1 break).
    I do not poses an at&t SIM.
    Can someone answer me? when I connect the phone, if it is not 3.1, will it tell me what version it is when asking to update?

    Go to Itunes, hold shift and click on the restore. Select the file you just downloaded. Tada. Now jailbreak.
