[...] The iPhone is the most recognisable smart phone in the world. Its popularity meant that it was the first phone that really was built for apps. There are now literally thousands of companies churning out hundreds of thousands of apps for both the iPhone and the iPod Touch. Many people have hundreds of apps on their iPhone for every task imaginable such as splitting up the cost of a bill, getting your horoscope or booking flights. But organising them can be an issue which can result in you messing up your app pages. [...]

ZEND, you are the man, thanks a bunch. But now, i only have one problem. The iphone gave me an error 1010 or something close to that, but that was after restoring the firmware back to 2.2 from 3.0. When i use QuickPwn 2.5.5 it wont detect my phone, what should i do. My phone is stuck with the itunes logo and a USB pointing to it!

if you want to downgrade you must uninstall itunes and Apple Mobile Device Support, restart and instal itunes 7.43, 7.7 or other older versions; now:
-Download the 2.2.1 (or 2.2) ipsw file for your phone.
Launch iTunes, connect to USB, and enter DFU mode (see below).
iTunes will mention restore mode. Click OK and then Shift-click “Restore”
-Choose the ipsw file you downloaded. Wait for restore.
If this completes successfully, congratulations! You’re done! If you get Error 1013 (as I did), ignore and continue.
-Hold the Power and Home button for 15 seconds, then press Power for 2 seconds to reset your phone.
-You should now have the “Emergency Call” screen. If your phone has service, it should activate itself.
-If you’ve switched phones (to a 3GS for instance), you will need to either purchase phone service for it, or activate it via jailbreak.
-Once activated, you’re ready to start testing!

ZEND OR ANYONE HELP ME

I got iPhone 3G 2.28.00 jailbreaked with yellowsnowed to put the firmware 2.20, then I Pwnaged a 3.0 firmware and restored with iTunes 8.2, later tried to unlock with ultrasnow, but still no carrier. I tried like 8 times to redo all but no success, then I tried to downgrade to 2.2.1 following your instructions, and Luis1’s as well:
- Used itunes 8.1
- Couldn’t get DFU white screen with any of the tools you say, but I could get it with RedSnow, and STILL, always get Error 20 from Any Itunes version, so I reasonably think I got an iBrick please could anyone tell me what is wrong, or if there is a solution for Error 20 from itunes? I think my big mistake was trying to see how 3.0 works in the first place, it sucks, its slow, drain battery, and it’s nothing amazing at all. Desperately Help!!

Cheers

With your help i found out a good solution working for me very well after 5 hour of trying :

1. I used Itunes 8.2 , why? becouse 3.0 is not recognized on 8.1 so
2. I used QuickPwnRC3 and 2.0.2 software no problem if not all installed just install
3. I uninstalled 8.2 and installed 8.1 (ITunes i mean) why? becouse 2.0.2 is not recognized by Itunes 8.2
4. I used winpwn-2.5-BETA with 2.0.2 firmware and got white screen as Zend say`d and
5. I push in Itunes Shift+ Restore and but 2.2.1 software and doing now restore..hope this will help . link for firmware and softs i used are on this page just search and u will find it!

Do i need to downgrade itunes?

By: luiss11

luiss11 — Wed, 01 Jul 2009 18:24:08 +0000

And i forgot to mention, after you sucessfuly downgrade to 2.2.1 you will need quickpwn 2.5

http://quickpwn2-2-1.googlecode.com/files/QuickPwn-225-2.zip
(WINDOWS)
http://quickpwn2-2-1.googlecode.com/files/QuickPwn_2.2.5.dmg
(MAC)

i have both MAC AND WINDOWS and i prefer to do all this on my Windows XP machine. My preference.

Guys here is the tutorial that ZEND gave us all but in video so you can see exactly step by step what you have to do , I had the same problem with my phone.
You need:
Itunes 8.1
http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iTunes8/061-6166.20090311.znt32/iTunesSetup.exe
Firmware 2.0.2
3G
http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone/061-5241.20080818.t5Fv3/iPhone1,2_2.0.2_5C1_Restore.ipsw
2G
http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone/061-5246.20080818.2V0hO/iPhone1,1_2.0.2_5C1_Restore.ipsw
Firmware 2.2.1
3G
http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone/061-5828.20090127.aQLi8/iPhone1,2_2.2.1_5H11_Restore.ipsw
2G
http://appldnld.apple.com.edgesuite.net/content.info.apple.com/iPhone/061-5830.20090127.Mmni6/iPhone1,1_2.2.1_5H11_Restore.ipsw
Winpwn 2.5
http://rapidshare.com/files/141607044/winpwn-2.5-BETA_2_Setup.zip.html

Here is a video tutorial showing you exactly how to do this:
http://www.youtube.com/watch?v=26BGUkjuAUg
Remember , when you get the white screen close winpwn 2.5 and open itunes , it will be recognized as a recovery iphone , there youll hit SHIFT + RESTORE ( BUTTON ) PC , ALT(OPT) + RESTORE (BUTTON) MAC, and select the 2.2.1 firmware that is for your cell phone , be it 2G OR 3G. I posted the firmwares for your respective phone seperately, remember to download the one for your phone because you will get errors , and do not use any other itunes other than 8.1, WHY? BECAUSE THIS IS HOW IT WORKED OUT FOR ME. GOOD LUCK TO EVERYONE!!!!!!!!

Follow all this carefully and you will suceed, we all hate 3.0 , causes battery drainage issues , and overheating problems ( at least for me ) . And we want to revert to 2.2.1.

when i use the restore, it doesnt show the file. it only shows the folders… iPhone1,1_2.0.2_5C1_Restore.zip is what i downloaded, then when i unzip it, it shows folder .fseventsd and Firmware. when i open firmware it shows all_flash and dfu folder, but when i open either it shows blank…. there is no IPSW file at all, i have tried several downloads from different site, it all shows blank no IPSW file. i have tried with WIndows 7, windows vista ultimate 64bit and windows xp nothing makes difference…

Does this method work for 3G iphones ?

I have tried loads of things and got error 20 / 1600 / 1602 and another one starting with X and a load of numbers and letters. so I downgraded itunes 8.1.1 because I heard that 8.2 was the problem, I got a couple of steps more but still ended up with error 1600 even when I used Pwnage Tool to put it into DFU mode.

Can anyone please help
