No, I don't have any idea why I did it. I'm bored and I've got some fancy ARM-based hardware -- it was bound to happen eventually :p

Anyways, some observations:

- It's way, way faster than 2.x. It's even slightly faster than 1.1.4 IMO.
- Transitions are different. They're slower, and (possibly) as a result they seem more fluid.
- Applications launch pretty fast. (As they do with all 1.x.x firmwares.)
- My Rebel SIM (v. 44) doesn't work.
- The "You need to activate" screen is laid out differently. The 'i' is in a different spot and looks different than it does with later firmwares -- it looks kinda sloppy, almost as though they didn't anti-alias the bevel of the circle surrounding the 'i'.

That's about it. Next up is 1.1.4, which I think I'll stay on for a while...

Just out of curiosity, what procedure did you follow to downgrade that far? Did you do a DFU+custom restore? Or is it more complicated?

First, I downgraded from 2.2.1 to 1.1.4 using the established protocol (documented elsewhere).

I used iTunes 7.5

Once I was running 1.1.4, I dropped into DFU and flashed 1.0. To my surprise it worked, but the phone hung on restart. I went back to DFU and reflashed 1.0. Once the phone rebooted, I was greeted with the "you need to activate" screen. I used ZiPhone 3.0 to activate it (I know... it's dangerous, but it was the fastest tool for the job, and this is my experimental phone, so I wasn't too worried...) After that, I was all set.
 
cmon dude. its valentines day, and you stayed at home downgrading your ipod's firmware. really?
 
Interesting. I wonder if this is possible to do on an iPhone 3G, just because.
How often does Safari crash?

No, why would he do that!? That's lame.
He spent his valentines day at home downgrading his iPhone's firmware.

You can download the software here:

http://www.felixbruns.de/iPod/firmware/

To install it, put your iPhone into DFU mode, you can use Pwnage tool to do this; Download here: http://iphone-dev.fgv6.net/PwnageTool_2.2.5.dmg

Then when your iPhone is in DFU mode, open iTunes, download the software, then click the "Restore" button on iTunes while holding the "Option" key. iTunes will then open a window in which you can select the software you want to installed. It will then install and your done.

That procedure doesn't always work, depending on the version of iTunes you have installed. Versions > 7.5 won't let you flash 1.1.4 to a device running 2.x. (IIRC) Versions < 7.7 won't let you flash 2.2.x. Plus, you can't downgrade from 2.2.1 to 1.0 directly. I know -- I tried.

That doesn't work for downgrading from 2.x.x to the 1.x.x firmware's.
 
Quick question did it change your baseband? Im wondering if anyone can shake the new 2.30 baseband.
