Please help. I updated my iPhone 4 from 5.0 to 5.0.1 via the Software Update on the iPhone. I'm not concerned about the baseband and unlocking as I've already had my mobile carrier unlock the iPhone. Anyway, with the iPhone already at iOS 5.0.1 I've downloaded the latest version of Redsn0w and followed the steps exactly (skipping the steps to upgrade to iOS 5.0.1 as it says). I've launched Redsn0w, clicked Jailbreak, put my iPhone into DFU mode and it starts to prepare the jailbreak and then prompts that the IPSW is needed...?? The tutorial specifically states that you do not need to download the 5.0.1 firmware if you are already on iOS 5.0.1 which I am. What am I doing wrong?

I'm having exactly the same problem. I tried twice plus I followed instructions to manually select isp* and files came up on my computer but nothing related to that. Do I need to reload 5.01? Any help is appreciated.

Since I'm new to this and it probably has been answered already I was wondering if I can unlock my iPhone 4g. It is w AT&T.. And currently has version 5.0.1. Modem firmware 04.11.08..... I got the phone from apple w these settings. Thank you in advance.

no way for now. the baseband is too new and can not be downgraded. either sell this phone and exchange for an iPhone 4 has baseband 04.11.01 or lower, like 03.10.01, jailbreak it, use Gevey; or wait for few more months and see if there is any new methods come out, and remember, never upgrade your iPhone! (unless do it with customized firmware)

cydia keeps on crashing each time :- 1) push the about button 2) try to add source 3) tap on the spotlight search area on the search tab is it just me or what

i experienced the same thing. so far the best way is making a customized firmware with cydia bundled by using pwnagetools. redsnow has bugs.

managed to solve the problem after trying this. dont know about other methods. Cydia crash 1. Connect the jailbroken idevice to your computer, run iFunbox or other files manger, and use its file management capabilities navigate into the /private/var/mobile/Library directory, copy the “Keyboard” folder to your computer desktop. 2. Go to /private/var/root/Library directory, upload just saved “Keyboard“ directory to this folder. 3. Reboot the device, then back into Cydia, the crash issue fixed.

All worked fine. iPhone 4, retained BB 3.10.01 using gevey sim. All worked perfect. however cydia does not work. Search in cydia does not show any results.

Soze - January 1, 2012 at 5:09am
Go to sources in Cydia, manage, edit and add the following: cydia.hackulo.us

I've iOS 4.3.3 JB, I tried to upgrade the firmware to 5.0.1 before I JB it, but now my iPhone stuck on iTunes Logo..... Can anyone help me ??
SleeperNinja - December 28, 2011 at 5:08pm
Update iTunes to current. Do the restore again, and don't restore from back up or unlock and setup iOS5 until AFTER you JB. I had a similar problem, the Apple logo was on like a 30 second restart cycle.

JB worked fine but there is a glitch, sometimes for some reason apps open up really small in the top left corner of iphone screen, have to boot in safe mode and reboot device to fix. something you guys might wanna look into. thanks~

I've got that too And once it has started it affects all apps. Thanks for the tip of going into safe mode though. That was a lifesaver!
