How to Upgrade iPhone 4 to iOS 5
SPONSORED LINKS
There are three ways to upgrade iPhone 4 to iOS 5 . All the methods are explained below . Upgrading to iOS 5 required iTunes 10.5 and a good internet connection to download the firmware files .
Method 1 : Update via iTunes Automatically .
- First download iTunes 10.5 on your computer (MAC – PC)
- Now launch iTunes and connect your iPhone to your computer using the USB cable .
- iTunes should detect your connected device and search for update . If not go to step 4 .
- Go to Help tab on the top of iTunes window and select “Check for Updates” as shown below .
- Now iTunes will connect with Apple servers and check for latest updates . You should soon be able to see an update notification window as shown here
Method 2 : Manually Update using iTunes and IPSW Files
iOS firmware files are also called ipsw files as they end with .ipsw file extension . These files can be downloaded directly from Apple Servers . iTunes update method explained above automates the downloading and selection of the right ipsw for your device . Follow the steps below to manually update using firmware files
- Download iOS 5 ipsw for your device (iPhone 4 3GS iPod Touch 4 3G iPad & Apple TV)
- Download iTunes 10.5
- Launch iTunes and connect your device .
- Now press SHIFT key on your PC keyboard/ ALT in MAC Keyboard and select UPDATE button on iTunes as shown below
- This will open a window for file selection . Navigate to the downloaded iOS 5 ipsw file and select it . The update process will now begin .
Method 3 : Upgrade to iOS 5 and Preserve Baseband
iPhone Dev Team has come up with new updated Redsnow 0.9.9b5 for Mac and Sn0wbreeze 2.8 beta 8 for Windows users which can create custom ipsw file that can be used to preserve baseband required fo Gevey Sim and Ultrasn0w unlock users .
Gevey Sim Users :
Thos who depend on Gevey Sim Unlock can use Method 3 explained above to update using Redsn0w custom iOS 5 ipsw file while preserving original baseband . Gevey Sim works only on baseband 04.10.01 and older. Directly updating to iOS 5 using the above mentioned techniques will update your baseband hence render the Gevey Sim useless .
iPhone Jailbreak Users :
Jailbreak users can follow the article here – Upgrade Jailbroken iPhone 4 for upgrading and preserving old jailbreak apps . Read our iOS 5 jailbreak tutorials for details.

Hi,
I have previously JB my Iphone 4 using redsnow. and now i tried using itunes to update to ios5 but it keeps on displaying an error message “error 3194″. Most of the guides ask to uninstall the unauthorized modified programmes. How do i do that? I tried to restore using itunes and still the same error message.
I cant upgrade iOS 5 ,it downloads fine but when it starts installing it says error (-39) and that there something wrong with the connection .
does any one know whats wrong .
I tried using the update and restore buttons and in DFU mode.
go my computer :C/system32/drivers/etc
and you will see the “host” file open it with notepad
add this ip: # 74.208.10.249 gs.apple.com at the end of the file
:C/windows/system32/drivers/etc
remmember to save Ctrl+S
good site for working jailbreak apps:
http:// cydia.myrepospace.com/ios5beta
u can install 3rd party apps and tweaks. like UIsettings and bbsettings
add to sources in cydia

I know ios 5 is released. I’m talking about the untethered jailbreak for it!

If I have an jailbroken iPhone 4 on 4.3.1 that works with T-mobile, can I still upgrade to iOS5, and have it work with T-mobile, still?

Okay! I have the same problem as you!
I have an iPhone 4 version 4.1 that works with Tmobile. I got it this February and I am so scared to mess up the phone if I tried upgrading.

Hi! I’ve noticed I did exactly the same thing as some people..
I upgraded my factory locked iPhone 4 – that was working with Gevey SIM – and now it’s not working.
What should I do? I’ll wait for the answer like the others..
am new to jailbreaking. I have a jailbroken iPhone 4.3.5 using redsnow and I would like to update to iOS 5. I’ve read about people having problems when they try updating their phone. I would like to get rid of the jailbreak because I’m selling it to get the new one. Thank you in advance.

Itunes Not Updating My iPhone 4.
Software Downloaded By Direct Download.
Showing 3002 Error.
Please Tell Me What To Doo..??
it is a temporary error , try again later at non peak hours
on mac. it is option+click on upgrade or restore. and not shift+click [that's WIN I think]. But if the device is already jailbroken, it is very possible that it won’t work though. you might just need to restore.
I have an Iphone 4 factory unlocked and Jailbreaked my current ios is 4.3.3 firmware is 4.10.01. I alrady back my iphone in Itunes. I jailbreak it using jailbreame.com and its working perfectly well.
Here are my questions:
1. Do i really need to update to ios 5?
2. Can I resynched all my applications from Installous and cydia to my iphone after i update my ios 5?
3. if the Iphone 4 is already jailbreak and I update my ios to 5 will it keep the same as jailbreak or I will jailbreak again.
Alla,
I would personally say no. You don’t NEED to upgrade to IOS 5. It still has many bugs, and many nice jailbroken tweaks crash the IOS because they are not compatible yet. JB developers are working on fixing their JB apps as I type this message.
SIRI is considered the most tempting feature in the new iPhone 4S, but you won’t, for while, get it on iPhone 4G. At the moment, Apple is only porting SIRI to iPhone 4S only.
I think you are in a really good spot with your 4.3.3 and unlocked iDevice as it allows you to have untethered jailbreak and jailbroken apps work great. I would recommend you to stay right were you are for a long while.
regarding your questions 2 and 3. You can sync back you cydia apps if you have backed up your apps with aptbackup or similar apps found in cydia. after backing up with aptbackup you need to back up your iPhone in iTunes.
After upgrading to IOS5 you will need to Jailbreak again. redsn0w 9.9b6 should work just fine.
Again, I would suggest no to upgrade to IOS5 at this moment. Especially, since you have 4.3.3 which allows you to jailbreaked untethered and jailbroken apps work. 4.3.5 and 5.0 are tethered jailbreaks.
Hi, I have a jailbreak(ultrasn0w) iphone4 version 4.0.1 firmware 01.59.00. Can I upgrade to iSO5 without losing my baseband? And if so do i just use itunes then jailbreak again, or do I need to use redsn0w or another method?
Thanks

Steve, You can use Redsn0w 9.9b6 or b7 [link below] to make a custom bundle to not upgrade your baseband when you install IOS5. But honestly, as I adviced Allan, I think you can stay in IOS 4.x.x and have an untethered jailbreak, and jailbroken apps that work great. IOS5 is still has conflicts with jailbroken apps. The apps are being fixed as we speak, so as long as you can stand some JB apps not working you should be fine updating to IOS5.
here you can download redsn0w .

Having Firmware version 04.10.01, Baseband 4.3.2 iPhone4 bought in US with carrier AT&T unlocked by gevey sim as per your suggestion. It’s working fine in Nepal downloading recent apps, however couldn’t dare to upgrade to higher versions. May I upgrade to iOS5 ? Whether it will pose any problem ? I need your guidance.
Thank you !
I have an iPhone 4 version 4.1.
Should I upgrade to a newer version or stay with the one I have now? I have an unlocked jailbroken phone that can be used for t-mobile. But I’m not sure about what these terms actually mean. As long as I have the phone and it’s in good condition I think I’m okay but with the new updates come out, I feel that my phone is getting old and everything. Should I update? And if I should, is it compatible with what I have?

I have a jailbroken iPhone 4 and I want to upgrade to the new IOS 5. I dont care about the baseband because I dont need it unlocked I’m with AT&T. My question is do I have to save my shsh blobs since it is already jailbroke and have used cydia which i know saves your shsh blobs when you go to there site on your iphone? I just want to upgrade that way if my phone shuts off while I’m away from my computer I can still use it with the semi-untethered IOS 5. I hope that I’m not too confusing on my question. Can you also give instructions on how to upgrade to the new IOS? I’m new to all this and did not jailbreak my phone until the 4.3.4 version. thank you
SHSH blobs is not really required if you dont want to downgrade
I have factory unlocked iPhone 4. I have jail broken using limerain1. The firmware on my phone is 02.10.04

Hi,
I am using Gevey Sim to unlock my iPhone 4 running on firmware 04.10.01 version 4.3.2. I want to upgrade it to iOS 5. Is it possible as I have not jailbreaked my iphone and I do have the orginal carrier of the phone. This iPhone is from Japan.
Your answer will be valuable.

I m going to upgrade my 3gs to ios 5
And can any1 tell me tht if upgrade with method 2
And in case
I want to downgarde my originial ios 4.3.3 ….then it is possible?
And
How can it is posssible?!!!!
I recently purchased a used but like-new iphone 3gs that had been jailbroken and unlocked, then upgraded to 5.0 while retaining the jailbreak. It worked fine for a couple of weeks, then permanently crashed while trying to update Apps via Cydia.
The Apple store replaced it for $150. The new phone is running 4.3.5. Problem is, I cannot synch and recover my apps unless I update to 5.0 (because that’s what my old phone was running).
I can pay the same guy I bought the original phone from to jailbreak / unlock, then upgrade to 5.0. However, I hate to destroy another phone if there are known issues with this procedure.
Has anyone experienced a similar problem? Any advice would be much appreciated, as I’m not a techy. Thanks.
