The hole in Safari has already been patched by Apple and they are preparing it for an upcoming software update, so make sure you back up your SHSH for your firmware so that you can restore back to it and use the JailbreakMe.com method to jailbreak your device. If your thinking of getting an iPhone 4 you better pick it up soon, because as soon as the new update is out you won’t be able to use the same exploit to jailbreak your phone.
On Wednesday an Apple spokeswoman said in a statement, “We’re aware of this reported issue, we have already developed a fix and it will be available to customers in an upcoming software update.”
For all those of you who have used the JailbreakMe.com method of jailbreaking then you took advantage of a PDF exploit in the Safari application. This is good that you can jailbreak your device so easily but it also means anyone with the right know how can run code on your iDevice. This means that if in the wrong hands it could be used for malicious purposes.
The iPhone Dev-Team or Apple will eventually patch the PDF hole, probably the latter. For now you need to make sure your device is protected so that you don’t fall into any malicious traps. You need to install a Cydia package called PDF Loading Warner, this package displays a pop-up when your device is about to open a PDF. It won’t stop this exploit but it will let you choose not to open a PDF that might be malicious. It has caused some issues with iBooks when opening PDF files as you have to dismiss the pop-up numerous times. However it’s a small price to pay for such an easy jailbreak.
The folks over at 9to5mac have found that FaceTime uses just under 3MB of data per minute. To be able to use FaceTime over 3G you need to jailbreak your iPhone 4 and then download the My3G app from Cydia. Then you can ‘trick’ the iOS into thinking it’s on WiFi when it’s actually using the 3G cellular network. Obviously this has it’s upsides such as using FaceTime where ever you like or watching high quality YouTube videos on the go. Bear in mind if your using FaceTime on 3G then take into your bandwidth cap into consideration. On O2 in the UK currently most iPhone 4 users have a 500MB+ cap. So if your on the 500MB plan then you can use FaceTime on 3G for a total of around 2 1/2 hours a month, that’s just on FaceTime. So make sure if you are using FaceTime on 3G that you don’t use it too much.
As I said in my last blog post, the Dev-Team have released the latest version of the ultrasn0w carrier unlock for the iPhone 4. Version 1.0-1 is now in Cydia and if it’s not then just add the repo666.ultrasnow.com repository. It works on the iPhone 4 with baseband 01.59 and on the 3G/3GS basebands 04.26.08, 05.11.07, 05.12.01 and 05.13.04.
