1. Find a custom 3.0 firmware for your iphone model created by a mac user.
2. download and install winpwn 2.5.0.2 from the official website.
3. download an older firmware supported by winpwn such as 2.0.2 as well as the bootloader files (3.9+4.6) if you have a 2g iphone.
4. use winpwn and follow the directions until it asks you to connect the iphone and go into dfu mode. the application will crash and leave your iphone with a blank white screen.force quit the app using task manager.
5. Now use itunes to restore the iphone with the custom firmware obtained in step 1.

Seems to be the easiest that I have tried yet and it worked the first time like a charm.

Thanks, this worked! I've only been at it for 10 hours or so!
I'm lucky I had both a Mac and a Windows box available. Presumably you could get to the white screen using this method and then take the iphone back to your mac to complete the upgrade.

I started out doing the upgrade without updating my iTunes to 8.2. This should be added to the guide. I don't know if this causes the 1600 problems or not.

During my many tries to get around the 1600 problem I was always able to do a factory restore with the original firmware. I was tempted to start that and then try unplugging the iphone at the right moment before it starts loading, then restart the restore with the custom firmware. Someone who is desperate might try this.

Again, thanks!

After reading all these posts I was very nervous about trying to update to 3.0. My phone has always been jailbroken and unlocked with PwnageTool, and was running 2.2.1. I'm on T-Mobile.

I updated my iTunes to 8.2.
I downloaded the new PwnageTool and the 3.0 firmware from Apple.
Ran the PwnageTool and made my custom firmware (I do have an Intel Mac).
After I had the custom firmware on my desktop, I plugged my iPhone into my Mac (no DFU business), and when my iTunes came up, I held down option and clicked on restore.

About 5 minutes later I'm updated! Put all my music, apps, etc back on, re-entered my APN.
Everything works.

Now I just have to add some third party apps and I'm set to go!

Worked for me: updated 2 iPhone 2G, only one asked for the bootloader files, other than that every thing seems to be working as advertised!

For those of you who are having problems with bootloader files: go back to page 5 or 6 of this thread, someone posted a link to iClarified with pretty much the same instructions, but with the bootload files. That solved my prob for one of the phones.

iPhone 2g (x2)
Intel MB OSX 10.5.7
iTunes 8.2

Thanks for the instructions - worked flawlessly. The only problem is that it's becoming really apparent that 3.0 was not meant to be used on a slow-*** processor like the one in the 1st Gen iPhone.

My phone feels like it's constantly lagging, apps are slow to open, delayed reactions across the board. I deleted all but a few of the apps I previously had on the phone in the hope that it would help speed things up. It hasn't.

Does anyone have advice on any other tweaks that might make my 1st Gen iPhone with 3.0 a bit more responsive? Many thanks.

i have the tzones plan, internet works wit 3.0 upgrade, just remember to go to cellular data network and put apn to epc.tmobile.com

[Oliver350Z]

The 3.0 is cool but...
I am seriously thinking about downgrading (if possible).

My phone also got really slow, and lagging to respond instead of being faster, as advertised.

Well it's only been 2 days, I will let it run for a week and then make a decision.

Thank you Dev team and forum members, I followed the instructions and walla now my iphone that was a 2.1 software is an unlocked jailbroken 3.0.

[trisksxm]

So far my iphone has actually increased in speed... but it's only been 2 days...

i agree.. my 2g is atleast 40% faster with all previous JB apps installed again.. including mobile install, cycorder, five icon dock, WB.. my iphone is exactly as before except 3.0 minus GBA..

[trisksxm]

...but I have noticed my battery life seems to be shorter than usual...

[hbelkins]

United States AT&T user, EDGE iPhone jailbroken, Intel Mac... I only want to Jailbreak, not unlock. What steps should I do differently than what are outlined in this tutorial?

I presume I should first update to the most recent system software and most recent version of iTunes before attempting to jailbreak my iPhone, correct?

I'm hesitant on doing this until I know it's foolproof because I depend on PDANet and don't want to lose the ability to tether my Mac using PDANet. I'm not interested in any AT&T tethering plans.

To all Iphone 2G users who wants to upgrade to 3.0 OS, you need to downgrade your "iousbfamily315.4.1log.dmg". This have an effect in properly putting your Iphone 2G in the correct DFU mode. I experienced it and gave me an error of unsuccessful DFU mode.

Hope this helps.....
