On Jailbreaking my iOS4.3.5 iPhone4..
Earlier this week, I jailbroke my iPhone4 iOS4.3.5 device. The jailbreak solution that is currently available for iOS4.3.5 is tethered jailbreak. If you are not familiar with “Tethered Jailbreak”, it essentially means that rebooting the jailbroken device would require it to be connected /tethered to the PC/MAC. This is of course not ideal but under the circumstances, this was my only option (And no-I couldn’t downgrade to iOS 4.3.3 for various reasons which are not directly relevant to this post).
Installing the jailbreak Software
I used Redsn0w V0.9.8b3 jailbreak tool. Follow the instructions provided here. The process is very straightforward.
Cydia Crashing Issue
Although the jailbreak completed successfully, the Cydia icon was white and it crashed as soon as I clicked on it. To get around it, I rebooted the device by running Redsn0w in tethered mode. Be sure to check the “Just boot tethered right now” option on Redsn0w . Once the device rebooted, the Cydia app started working. No more crashes. I was able to download and install apps. Unfortunately, some of them required a reboot and I had to go through the tethered reboot process again
The MobileTerminal, OpenSSH and Aptupdate for SBSettings were among the packages that I installed. These packages will come in handy as you will see below.
Installing third party apps directly
Next, I wanted to install a third party app directly to the phone. The third party app was not available through Cydia sources or the AppStore.
For this, I copied the .app file corresponding to my app into the /Applications folder on the iPhone , created the /var/mobile/Documents folder and updated the file permissions by running the commands listed below from a terminal window on my MAC. Ofcourse, I substituted "IPhoneIPAddress" with the IPAddress of my jailbroken phone while executing the commands

1 2 3 |
scp -r MyApp.app root@<iPhoneIPAddress>:/Applications/ ssh root@<iPhoneIPAddress>:/'chmod -R 755 /Applications/MyApp.app' ssh root@<iPhoneIPAddress>:/ 'mkdir /var/mobile/Documents;chmod -R 777 /var/mobile/Documents' |
Note: Creation of the Documents folder is required only the first time (unless you delete it between installations)
I rebooted the device in tethered mode. When the device rebooted, the app was ready. I could launch it and run it.
So far, so good until..
I tried to launch Cydia app, it crashed. All the other apps on the phone worked as normal.
Cydia Crashing Issue..Again.
So I rebooted the phone again in tethered mode. This time the reboot had no effect. The other option was to re-jailbreak but I did not want to do that just yet.
Instead, I uninstalled and re-install the Cydia app by running the following commands from the terminal window of my MAC. I substituted "IPhoneIPAddress" with the IPAddress of my jailbroken phone while executing the commands
|
1 2 3 4 5 |
ssh root@<IPhoneIPAddress> apt-get remove Cydia killall –HUP SpringBoard apt-get install Cydia killall –HUP SpringBoard |
Note: The AptUpdate for SBSettings that I installed earlier automatically installed the apt tools .
Once I did that, cydia was back up and running again. I currently have version 1.1.1 of Cydia on the phone. Everything else continues to work as expected.
Now, its appears that installing the third party app caused Cydia to crash but it is unclear to me why that was the case because Cydia started working again after re-installation and the third party app continues to work as well. In any case, now I know what I should do to resolve the problem should it resurface but its less than ideal.
In Conclusion..
With the number of reboots that I had to do, the tethering is especially tedious. If you are considering jailbreaking your iOS device, I would recommend that you refrain from updating it to 3.4.5. for now and wait for an untethered release of jailbreaking software if possible.
