Jailbreak your iPhone
hi dont know much about this stuff I have a iphone 2g running on version 1.1.3 and want to upgrade it, how do i do it without
1. losing all of my contacts photos etc as if I sync with itunes it will lock it
2. how do I back up my files
3. if i do upgrade will I ever be able to use itunes to put music etc on iphone and save files without fear of locking the iphone
thanks
I am heading to thailand shortly i have heard they can do this for only a few bucks has anyone tried
okay i’m really excited to update to 3.0 for the 2g! because of the landscape keyboard on all apps/copy & paste. i used quickpwn 2.2.1 on my iPhone 2g on windows. my question is if i can could just update my 2g(2.2.1) to 3.0 without quickpwn’ing it again? or is it safe?

I read your guide. If I understand you correctly, your guide to downgrade it to 2.02 is for activating the phone. If my phone is activated + unlocked @ 2.2.1, do I still have to go through those steps? Can I go straight by loading 3.0GM with iTune 8.2?
BTW, I didn’t quickpwn my 2.2.1, I downloaded custom 2G 2.2.1 firmware from the web which I believe all the custom firmwares are created with pwntool, right?
@ Eddie Yes custom .ipsw are created by Pwnage tool but i m not sure about custom to 3.0 upgrade. Custom firmware can be used with a quickpwned iPhone too. You can try a simple update if works fine otherwise do a downgrade to 2.0.2 in DFU mode then follow the procedure.
If you’d like to take my opinion stick with your current firmware and wait for OS 3.0 final release it’s only one week far
@Johan @Eddie Yes this trick works with 3.0 GM too i’ve tested it on my iPhone 2G very first day but i think it will be good to wait for final release and jailbreak. BTW just posted a slightly modified guide.

John, how is it? I got the 3.0 GM firmware and I am using unlocked 2.2.1 right now. I just want to know if I can upgrade if I don’t care about jailbreaking. I need it to remain unlocked, that’s about it.
Testing this process now with iPhone 2G and new RELEASE of OS 3.0GM (Gold Master).
Will Post soon just Building a a clean custom 2.0.2 IPSW file
The procedure (iPhone 2g 2.2.1 QuickPwned to 3.0 Beta on Windows Computer) works for beta 5!
Note: in the first step, DFU mode is not necessary
Note: in the second step I used QuickPwn 2.2.5-2 (instead of 1.0)
Seems to be working..
But, icy or Cydia doesn’t come with the upgrade.
Let’s hope 3.0b5 is more stable than b3.
so if im not mistaken, you have to have a have your udid activated with the developer program? so not anyone with an unlocked 2g can upgrade to 3.0 just to have it?
Hello
Is correct your information, I did the process with my iphone 2G and my iphone is unlocked, remember use the firm 2.2.1 Pwend, and then use Update button not Restore.
@ Fransisco Many peoples QuickPwned 2.2.1 encountered with error 1604 while upgrading to 3.0 So we recommend to restore-downgrade-update trick.
If you used Pwnage 2.2.1 then no problem go ahead with a simple Update.
