Ask Tii - Issues Upgrading and Jailbreaking iOS 5.0.1

Hello Rob,
 

Reading your instructions on Jailbreaking and Step 0 was funny, however, it appies to me. I currently am running iPhone 4 (AT&T) iOS 4.1(8B117) Firmware 02.10.04 Jailbroken with Limerain and my wifes iP4 I believe is 4.3 JB with Greenpoison. Was never really necessary to unlock.
 
 

My question is how do I go about upgrading those? I tried to restore yesterday and got stuck in restore mode. I downloaded Redsnow and the 5.0.1 IPSW. Whether I tried to restore with the downloaded IPSW or just plain restore, got several errors.  If I cannot restore, how do I unjailbreak to upgrade?
 
 

I have been following and learning the JB stuff for quite a while, (aside from our phones and iPad, I have helped many of my friends once they saw what our phones can do) but I apologize for what may be a stupid issue.  I just have not found an answer for my situation online and this is the first time I have wanted to update.
 
 

Thank you for any help you can provide.  If you need more info, would be glad to provide.

Hi John,

 

First off - what I am going to tell you to do - to update to iOS 5.0.1 - will not just remove your current jailbreak (until you add in a new one) - but it will remove the ability for you to unlock your iPhones.  If you do not care about unlocking your iPhones - then please proceed.

 

First connect your iPhone to your computer and launch iTunes.

 

Next when you see your iPhone under Devices on the left hand side - right click on the iPhone and select "Backup"

 

Once it is done backing up.  On the right hand side select "Summary" Then select "Check for update" 

 

Then follow the instructions for updating to iOS 5.0.1.

 

Once you are updated you can then go back to my tutorial to re-jailbreak.

 

Good luck.

 

Regards,
