The whole article talk about baseband downgrade. Notice that all the guys who did that mentioned iPhone 3G 2.2.1 firmware. This is why the article specifically mentioned that they have managed to downgrade the baseband from 2.3.03 to 2.28.
It is not false hope when many of them have done it.

One of our readers, ezio-xb just commented on our step-by-step guide to downgrade from iPhone firmware 2.2 to 2.1 to tell us that he was able to successfully downgrade his iPhone 3G back to firmware 2.2 and jailbreak it. We have updated the guide to downgrade from iPhone firmware 2.2.1 to firmware 2.2.

He commented:


"FYI; I just made the BIG mistake to update my Jailbraked 3g-iPhone with 2.2.1 (with the Safari blah blah update) which totally mess up my phone and put it back to "normal".
I found your guide and I downgrade back to 2.2 using the ...shift+restore option that you suggest for previously firmware in the upper article (!than you!)
After all the process and the long restore point I was able also to Jailbreak and now works as it was before and just need to fix my icons."



Notice the word 3G in the article that was first downgrade & jailbreak. ezio-xb initially has a non-working iPhone 3G when he mistakenly upgrade to firmware 2.2.1. The dead iPhonei s now working for him.

illjuan3@yahoo.com... posted a youtube video of the exact sequence of doing the restore & users skp, dm0ney, effwg etc... and many of the posting in the same page showed that they have manged to downgrade & un lock the iPhone 3G.
Even in the posting for te video in Youtube at least 1 of the recent posting thank the person for the intructions to solve the 2.2.1 downgrade probl

SO THIS IS NOT FALSE HOPE. AT LEAST THEY TRIED AND GET IT WORKING.
Just to let you know - I have unlocked, jailbreak and customized 5 iPhone 3G and 8 iPhone 2G over the last 4 months for friends & relatives for free. I am also a registered Apple iPhone Applications developer on iPhone applications as a part-time basis and also work on cracking some of the paid applications on Cydia & Applestore for my own personal use.

wow, so darn impressive!

Wow..5 3G iPhones and 8 2G iPhones consider alot?? Darn... you're no where near compare to Hanxz mate. Please keep your pride to yourself. Btw, if you post any crack apps or links, i will personally report you to the mods. Just a humble reminder.

Anyway, since you consider yourself a great master in iPhone, please help hanae0711 to downgrade. He may not be ready for such attempt and since you're good at it, lend him a hand.

Cheers

WOHOOO Thats great. I've never jailbreak or unlock any iphones before, heck i don't even have or hold an iPhone before. Nice touch on CRACKING paid applications. We need more pirates in this world. Ahoy there matey.

I think you or those people in the article should join the Dev team since the dev team themselves can't downgrade the baseband (or so they said).

I'm no iPhone expert but I do read a lot about it and I know what I'm talking about.

READ AND READ AGAIN THE QUOTE ABOVE DIRECTLY FROM DEV TEAM BLOG!!!

Clearly you don't understand the situation. TS want to unlock his phone since its an US set (locked to AT&T) and yellowsn0w does not work with 02.30.03. From the article (that has been your source), it's said that they manage to downgrade the FIRMWARE ... for goodness sake ... FIRMWARE and not a single hint of BASEBAND uttered in there. FIRMWARE can be downgraded but not BASEBAND. Get that thru you thick skull.

Please show me in any of the article or youtube or whatever that they manage to downgrade the BASEBAND ... again I said BASEBAND. If you keep insisting that it can be done ... I would gladly pay you on behalf of TS to unlock his 02.30.03 BASEBAND for RM100 since you said you do it for free.


P/S - I'm also a developer and cracking Apple apps are easy when crackulous is around. Big deal.

Added on February 6, 2009, 1:46 amTo add some more salt to the wound, I can even restore back the phone down to 1.0.2 but the baseband would still be 02.30.03 (but there's no firmware 1.0.2 for iPhone 3G ). The A17 testpoint is no use to clear the baseband since its using a different architecture from the 1st gen.

basically, you now have a glorified ipod touch
2 things u can do

1. get a turbo sim (As everyone here will say, NO)
2. wait for dev team to come up with a yellowsn0w update to work with the new baseband.

and yes what some of the forumers said before, 2.2.1 is a yellowsn0w killer
apple quietly released it.

i guess chrisl_57 didnt even know the existence of yellowsn0w..still using 2.2 turbosim..
or u got problem using yellowsn0w bro?

btw, if TS can even downgrade the firmware, it wouldnt make any different at all since yellowsn0w only unlock up to 2.28..no further than that..

Cheers.

i assume u don't read carefully on those article released by DEV TEAM...... please bear in mind once u upgrade d baseband to 02.30.03 there is no way to downgrade d baseband back to 02.28.00 (at d moment). d whole article is only talking about firmware downgrade n not baseband downgrade...
if u think so easy to downgrade d baseband then y should apple released d baseband upgrade? is it for fun? difinitely to kill yellowsnOw user....
..get your fact right before giving any comment..
by the way if u want to prove us wrong.....why not u upgrade your lock iphone to 2.2.1 using itune and later downgrade it to 2.2 n show us d baseband

cheers...

it definitely sounds like a swell plan
