iPhone 3G 02.30.03 Baseband Downgrade [How To]

After testing phasebanddowngrader by pH and not having any success I decided to skip using his script and start fresh using the GeoHotz method, the end results were success! I have therefore decided to write my own script, as I felt pH left out some important features from his. I also tried "DownBB" with no success, and felt that there was not enough documentation for any of these tools.

The posts in the comments by users that tried and failed seemed to support my theory.

I will have a much more detailed guide for those that wish to downgrade.

Please keep in mind this is only for iPhone 3G's running the 2.2.1 (5H11) Firmware with the 02.30.03 BaseBand, and the 5.08 (5.8) Boot Loader. Don't worry, I will go over how you can find all this out.

3G Downgrade Pro is quite simple, and I plan to continue working on improving it further. I'm currently working on a GUI version, but this release has already been delayed for over 2 weeks as it is, so I'm releasing this version first.
I have tested this software thoroughly to ensure a smooth release but I somehow expect some users may encounter issues, if this is the case, please report the errors or any questions/difficulties you are having to me.

UPDATE:
It seems w1kedz and DHowett have worked together and created a GUI BaseBand Downgrader, and it will be released today via CYDIA in BigBoss's repo (I assume)

Congrats to the both of them!
If it works fine and I don't see any issues, I won't release mine. However if I do find some issues, I may at that point release my downgrader.

iPhone Firmware Easter Egg?

"Re: 3G 02.03.03 Unlock"

It seems during my tests to unlock this phone and downgrade the 5.9BL I discovered an Easter Egg, rather then an unlock. (What else was I to think?) A Rogers Locked iPhone 3G running Firmware 2.2.1 with the 02.30.03BB OOB can without hacks/unlocking run "Pay as you go" cards from *SPEAKOUT*. I did a little digging and it seems that SpeakOut pays to use the Rogers Network. Interesting no? I wonder what other sims will work OOB on locked phones world wide.

iPhone 3G Developments

I've been too busy to post lately so forgive me for the dead air..

I've started using IRC again, though not using my old reg'd nick so I'm no longer
a higher power in the channels. But it was never something I asked for, It was always given,
and op or not I could care less, however there are some annoyances that come without ops,
such as lippy n00bs and other members with privs that wern't around back then, or just don't know me.
(My fault for changing my nick. "Privacy issue")

Anyways, I was talking in the channels with pH and tested a script he made based off of GeoHot's
exploit. It worked and made me focus on improvements as well as trying to downgrade the 5.9 boot loader to 5.8
since I had previous experience in the old 1.x days helping out the dev team.

There was allot of drama (Why I left) back then and people went separate ways (#mini-devs) etc

Well I'm not scared to brick my iPhone, because it's rather hard to do, and even in it's so called bricked state I've
risen it from the dead, so with all the tinkering I was doing I noticed my iPhone 3G was now displaying my pay as you go
carrier, but I was still on the 2.30.03 BB, so it seems I had unlocked the BB and getting all excited I burst out with excitement in the channel that I had unlocked it, and of course I was flamed. I did try to take video footage, but sadly its crap, and no one likes screen shots, so what did I do to unlock the iPhones 3G running 2.2.1 & 02.30.03 BB....

I have no clue!
I was simply using old and new tools to erase the BB and upload a new one, and now I can use my "Pay as you go" sim.

Do I care if no one believes me? No.

Will I release my unlock?
Sure, even though the community wasn't very supportive, I just have to try and retrace my steps.

I'll post some screen shots, bbinfo from minicom, logs video what ever I can think of to help you belive its real.
But I won't bend your arm behind your back, so if you choose to remain in disbelief, so be it, I really don't give a shit :)

iPod Touch 2nd Generation Jailbreak - The Solution!

[Sorry it's been forever since my last post.]

The iPod Touch 2nd Generation will here after be known as the IPT2G.

I've been sitting around brain storming and messing around with code
for the last few weeks, and I have finally come up with what I believe
is the answer to the current IPT2G jailbreak issue, and by issue I'm
of course speaking about the need for a tethered computer.

I first started working on having my old Palm M505 running OS4.1
boot the IPT2G using a specially built serial cable, but while this
may have been fine for me, not everyone has an old palm laying around.
And not only that, but why on earth would you want to carry around another bulky device!?

And while I'm sure you could fashion a nice compact dongle into a keychain
I've come up with something far better.

I'll have more details posted soon.
