Jailbreaking iOS 4.3.1 with PwnageTool 4.3

PwnageTool and Redsn0w have been updated, and both allow jailbreaking a range of iOS devices without tethering. This walk through covers PwnageTool 4.3, with another covering Redsn0w to follow. The main difference between the two apps is the method of jailbreaking. PwnageTool makes a custom Firmware file that iTunes puts onto the device. Redsn0w jailbreaks a device after iTunes has installed a standard Apple Firmware.

Before starting a jailbreak using PwnageTool or Redsn0w you need the correct firmware for your device. I used a great guide at iClarified that links to every iPhone firmware that has been released. My iPhone is a 3GS so the firmware I wanted was the 4.3.1 (3GS): iPhone2,1_4.3.1_8G4_Restore.ipsw. Once downloaded and placed on my desktop I launched Pwnagetool 4.3.

iOS 4.2.1 Jailbreak released

New Firmware, New Jailbreak. Following yesterday’s release of iOS 4.2.1, redsn0w 0.9.6b4 is now available to jailbreak it. There are some conditions attached, so best read the post at the iPhone Dev Team Blog before attempting the jailbreak.

Another thing to remember is that this is still beta software, so may not work as expected. I followed the instructions the app gives to enter DFU mode, but found redsn0w stopped at the waiting for reboot screen. I got around this problem by putting my iPhone 3GS into DFU mode manually before running redsn0w, then pressing the power button when redsn0w stopped at waiting for reboot.

Once Jailbroken, there are a few more issues. SB settings isn’t currently working for me, and crashes springboard when I try to use it. No doubt this will be quickly fixed, but for now just remember this is new software, so either wait for the jailbreak ecosystem to catch up or enjoy the ride.

Update 25th November – Cydia updated SBsettings Toggles today, and SBsettings is now working perfectly with 4.2.1 on my 3GS.

iOS 4.2.1 released today with free Mobile Me Find My Device

The release of iOS 4.2.1 is imminent, and the surprise is that with it comes the first free Mobile Me feature. Find My iPhone is now available to all iOS users without paying a Mobile Me annual subscription, and is easily set up from an iPhone/iPad/iPod using an existing or new iTunes account. Here’s a quick walk through of the steps using an iPad.

JailbreakMe.com for iOS4 (and 3.2) devices

The iPhone Dev Team has announced that jailbreakme.com is now live offering a Safari based jailbreak for iOS4 devices, as well as iPads running 3.2.1. Their blog post states the site will jailbreak iPhones, iPod Touches and iPads so it may work with older software versions but details are a little scarce at the moment.

The screenshots above and below show the simple jailbreaking process on my 3.2.1 iPad which now has Cydia installed as well as the marvelous iFile.

iOS 4.0.1 and iPad 3.2.1 released

Software updates for the iPad and devices running iOS 4 are now available through iTunes.  iPad OS 3.2.1 includes fixes for Wi-Fi, handling of PDFs in Mail and video playback, as well as adding Bing to Safari’s search options. iOS 4.0.1 for iPhone 4, 3GS and 3G lists an improvement to the formula used to calculate the signal strength bars as the only change.

I’ve just updated my 32Gb WiFi only iPad to 3.2.1, losing the Spirit jailbreak. I’ve found the benefits of a jailbroken iPad to be limited so far, so intend to wait a few months for the bugs to be ironed out of existing jailbroken apps.

Camera Connection Kit with iPad and iPhone Review

The main accesory I wanted to buy with my iPad was the camera connection kit. Unfortunately this was sold out in New York, so I tried again on launch day in the UK. When the kit sold out in a couple of hours here it was time to place an order through the Apple online store and wait three weeks like everyone else. I’ve now had the kit for two weeks and can give some thoughts on it’s use.

The camera connection kit comprises two small adaptors that plug into the iPad dock connector, providing an SD card slot and a USB socket.

The intended use for these two items is to transfer photo and video content from your digital camera to the iPad for viewing, storage and subsequent transfer to a computer. The first thing I tested when the kit arrived was its ability to import media from my Panasonic LX3 camera. Jpeg and RAW images preview and copy to the ipad correctly, and the camera’s 720p video is also fully supported. This wasn’t a huge surprise as much has already been written about the functionality of the kit, but being able to copy party video’s quickly to the iPad for immediate viewing was one of those ‘wow’ moments for the guests.

Jailbreaking a 3GS with iOS4

With the iPhone Dev Team’s release of PwnageTool 4 yesterday (and the 4.01 update today) I was ready to jailbreak my iPhone 3GS. It’s been running the iOS4 beta 4/Gold Master since that was leaked, but being on iOS4 already had prevented the use of the beta jailbreaks available before the public release of iOS4. There were still several steps involved to achieve the jailbreak, as stipulated in this condition from the Dev Team’s blog:

If you have a Jailbroken iPhone 3GS with the OLD BOOTROM and you DID NOT use Spirit to jailbreak then you can create the ipsw with PwnageTool 4.0 and restore with your jailbroken recovery mode

My 3GS uses the old bootrom, so OK there. The requirement for a jailbroken 3GS NOT using Spirit meant the first step was to downgrade the firmware to 3.1.2. That’s an easy step if Cydia has your SHSH stored for the previous firmware, as mine are.

The next step was to jailbreak the 3.1.2 install using redsn0w 0.9.2. Once this was confirmed to be working correctly (just look for Cydia to be installed) PwnageTool 4.01 was used to produce a custom iOS4 ipsw. The iPhone was then put into DFU mode, and iTunes used to pick the custom ipsw to restore.

Both times I restored a firmware during this process a 1015 error was given after the restore. By that time the restore had successfully completed but the iPhone was stuck in recovery mode. The freeware RecBoot utility was used to get out of recovery mode and back to normal startup.

A backup had been made by iTunes before starting the jailbreak, so this was restored once the jailbreak was completed. I now have SBsettings back on my iPhone, giving fast access to 3G and WiFi on/off to help conserve batter power. There’s a few other useful jailbroken apps that haven’t been updated for iOS4 compatibility yet, but hopefully that will be done soon.

Once again thanks to the iPhone Dev Team for redsn0w and PwnageTool, and to Saurik for Cydia and enabling the downgrade to earlier firmware.
