Hey Calichick213,
Try installing Poof or SB Settings from Cydia and using them to unhide your
apps and folders. This was a suggestion by Aragorn121, one of our readers
for a similar issue. -
Hi, I think that I have made a huge mistake .. am not sure !! I have an iPhone 3G, and it was on the 2.0 version .. so I used this tutorial to update it to 2.2.1 (Jailbreaking) and everything worked just fine, but when I tried to Unlock it using YellowSnow but it didnt work, even after switching off the 3G and the PIN Code ! Here is my iPhone info.: Version: 2.2.1 (5H11) Modem Firmware: 02.08.01 Pleas I need your help ! -

jeffwg thank you so much!i have updated the post following yout instructions, it works!

i have to wait <"~")!!!!! -
The downgrade from firmware 2.2.1 to 2.2 works on mine. However, SAD to say the baseband is still 02.30.03. So yellowsn0w does not work.
Is there a way to restore to default factory settings or even downgrade the baseband?
Need Help!

Hey nick,
There is currently no method available to downgrade the baseband. We will
keep you posted in case someone figures something out. So stay tuned here at

Greetings fellow funsters, so, ive used the new pwnage tool to upgrade to 2.2.1 and it worked beautifully, nicely jaolbroken .. HOWEVER ... i cannot unlock my phone and the modem firmware is 02.11.07 .. VERY confusing indeed. Do any of you clever chaps have any suggestions for a poor iphone rookie please? I use a Mac laptop. I've no choice but to 'hack' my phone, I live in Dubai and the iPhone isn't support here in the dessert yet ...... Any help would be greatly appriciated. Cheers, Martitishka :)

Hey martitishka,
You have not been able to unlock iPhone 3G as Dev Team's yellowsn0w
application can only unlock baseband 02.28.00.iPhone firmware 2.1 came bundled with 02.11.07, firmware 2.2 came bundled
with baseband 02.28.00 and firmware 2.2.1 comes bundled with baseband
02.30.03.So looks like you were on firmware 2.1 before using the custom firmware
created using the PwnageTool to update your iPhone with firmware 2.2.1 and
preserve its baseband. So though your iPhone 3G got upgraded to firmware
2.2.1 using the custom firmware, your baseband remain untouched at 02.11.07.You should first update your iPhone with firmware 2.2 (you can use this
guide) so your baseband gets updated to 02.28.00 and then restore your
iPhone using custom firmware created using the PwnageTool. After your
baseband has been upgraded to 02.28.00, you should be able to unlock iPhone
3G using Dev Team's yellowsn0w app.Please remember to follow the instructions very carefully.

IT WORKED FOR ME TOO. I had to scroll down after a few tries and Quickpwn it, but it worked. I still need to unlock because I bought it off ebay already updated to 2.2.1 and the unlocked baseband. Thank you for the tip Iphonehacks.

HELLO! GUYS .
i NEED SOME HELP FROM YOU ALL.
I DOWNGRADED IPHONE 3G fIRMWARE from 2.2.1 to 2.2: but the modem firmware on my iphone 3g stays the same as 02.30.03 . when downgrading to 2.2 the modem firmware should change to 02.28.00
what should i do next?
anything would help -
how go for dfu mode

Here is something new development and I need somebody to help me cause I think we are just to resolve it.
1. I try downgrade the modem 2.30.03 to 2.28.00 by copy BBUpdaterExtreme, ICE2_2.28.00.eep, ICE2_2.28.00.fls (there were quite several forum share this, kindly find your self) - So the first I did with the SIM card install, I don't know what happen and need manual restart. (I think this is some thing wrong, it should restart auto matically)
2.I redo the above and awsome, it restart by itself. This step actualy replace as much 2.30.03 file and replace with 2.28.00.
3.Using itune, I restore 2.2 version with iPhone1,2_2.2_5G77_Restore. with out SIMcard.
4. Amazingly there were no error (10xxx) apear and my 3G 8GB 4 days ago I bought in China with $700 restart normaly with the small lock icon at the middle top and message "No SIM card Installed, Insert a valid SIM with no PIN lock to activate iphone!!" with the background picture itune icon with USB and some small white arrow up.
5.I stuck here mannn, but I dont know yet what is the modem version now, since when I try to slide unlock, it goes to emergency call only.
6. So I plan to use Quickpwn225-2 and see what happen may be I can use back the yellwsnow

What is the thing to unlock 3G iphone?
-
Thank you, thank you. Got my 2G up and running again, thanks to your advice. LESSON LEARNED: DO NOT UPGRADE!
By the way, it's no longer necessary to downgrade from 2.2.1 on the 2G. QuickPwn ran with 2.2.1 on my 2G (Mac)
Cheers guys.

THIS REPLY IS ON MAY 15 2009. SORRY FOR ALL THE CAPS JUST WANTED TO TELL ALL IN A HURRY. I FIGURED IT OUT. WHEN YOU DOWN GRADE TO THE 2.2 FIRMWARE THROUGH ITUNES YOU WILL MORE THEN LIKELY GET THE 1013 ERROR, BUT DONT WORRY, I JUST DID. CLICK ON THE OK FROM THE 1013 ERROR AND CLOSE ITUNES, THEN OPEN THE QUICKPWN 2.2-1 PROGRAM, THE BOX WILL APPEAR SAYING TO HOLD DOWN THE POWER AND HOMEBUTTON FOR 15 SEC THEN THE POWER BUTTON FOR 2 SEC, CLICK OK FIRST THEN (LISTEN VERY CAREFULLY) ONLY HOLD DOWN BOTH BUTTONS UNTIL YOU SEE THE WHITE APPLE APPEAR ON YOUR SCREEN THE LET OFF THE HOME BUTTON AND HOLD THE POWER BUTTON FOR 2 SEC. NOW YOUR PHONE WILL BE IN THE ACTIVATE MODE AND NOT THE ERROR MODE. NOW USE THE QUICKPWN TO JAIL BREAK YOUR PHONE, JUST DID IT AND I AM NOW JAILBREAKING MY PHONE WITH THE 2.2 AND NOT THE 2.2.1 FIRMWARE. ENJOY!!!!!!

IT DID NOT WORK FOR ME IT GOT TO THE POINT WHERE IT SAID ERROR 1013 BUT WHEN I UNPLUG THE PHONE N RESTART IT IT ASKS FOR THE PHONE TO BE PLUGGED IN AND WHEN I DO THAT IT WILL NOT DO ANYTHING UNLESS I RESTORE IT BACK TO 2.2.1
